Chapter 1. INTRODUCTION

1.1 Overview

Phase combining is a traditional technique that cost effectively increases the available output
power of an amplifier system. The PCB-4000A 1+1 Phase Combiner (Figure 1-1), together with
two Solid State Power Amplifiers (SSPAs), form a complete 1+1 phase combined system that
doubles the available output power. The PCB-4000A also features a “soft fail” configuration; i.e., if
one SSPA experiences a failure, the total output power will be reduced by only 3 dB, rather than
6 dB.

Figure 1-2. Combined System Block Diagrams

PCB-4000A 1+1 Phase Combiner
Revision 2

The block diagrams shown in Figure 1-2 depict the major components of the 1:1 phase combined
system. (These diagrams employ High Powered Outdoor Amplifiers (HPODs) as the designated
SSPAs.)

The Phase Combiner Control Box (PCCB) contains a microprocessor-based Monitor and Control
(M&C) circuit board to control the system. Interconnection is as follows:

• The PCCB communicates with each SSPA via control cables that are attached from the
PCCB “SSPA COM 1 | J2” and “SSPA COM 2 | J3” co nnec tor s to each S SP A.

• Through this connection, the PCCB receives its prime power to operate. A +24V signal
from each SSPA is diode OR’ed to provide redundant operating power for the PCCB.

• A “Y” cable connects to the “SSPA SW OUT | J5” connector for control of the waveguide
switches. M&C communication with the PCCB is accomplished via the “SYSTEM COM |
J1” connector.

To avoid ambiguities, all communication to each SSPA is also accomplished via
the PCCB M&C.

The PCCB provides a weatherized housing for the necessary input RF components. System
interconnection is as follows:

• An input RF redundancy switch, controlled via the “RF INPUT SWITCH | J6” connector,
selects which RF path is directed to the output.

• The output RF signal is fed into an in-phase divider, which equally splits the signal in
phase and amplitude to the “SSPA OUT 1 | J9” and “SSPA OUT 2 | J10”
output connectors.

o The RF path to the “SSPA OUT 1 | J9” output connector contains a manually

adjustable phase shifter. This phase shifter is used to equalize the phase difference
of each SSPA signal path to achieve maximum system output power. It is accessible
via a small cover panel. This critical component is factory set and should only be
adjusted, if needs arise, by carefully following an appropriate alignment procedure.

See Chapter 3. OPERATION and ADJUSTMENT PROCEDURES for
operational and alignment information.

o The RF path to the “SSPA OUT 2 | J10” output connector contains a length of

coaxial cable that is factory manufactured to provide equal phase length paths from
the RF input to each PCCB output when the adjustable phase shifter is set to its
midpoint. This provides a maximum adjustable phase range.

There are also several isolators inside the PCCB that maintain good system Voltage Standing
Wave Ratio (VSWR). Do not alter any RF cable inside (or outside) of the box that is part of the
RF signal path.

• The RF signals from the PCCB are fed to the RF input of the respective SSPA via a set
of phase-matched cables. Again, the phase length (and matching) of these cables is
essential to system operation and no substitutes should be used. The routing should not
be such to cause extreme bends.

• The output waveguide combining system consists of balanced waveguide lengths, two
waveguide transfer switches, a “Magic-Tee” combiner with termination, and couplers for
test and alignment.

Introduction 1–3 MN-PCB-4000A

PCB-4000A 1+1 Phase Combiner

Phase and gain equalization are performed at the factory, and no user
such as the phase combiner box, needs to be replaced.

Revision 2

1.3 Theory of Operation

As mentioned previously, phase combining is a common technique to increase the available
output power of an amplifier system. Referring back to Figure 1-2, when two signals of equal
phase and amplitude are fed into the “Magic-Tee” combiner, the individual power of each SSPA is
summed at the output port and cancelled in the termination port.

In real systems, the phase and amplitude of the two signals are never exactly equal, so there is a
small amount of power that is absorbed by the load termination. This terminated port is
sometimes referred to as the “wasted” power port. In practice, however, it is possible to keep
phase and amplitude imbalances at low enough levels such that overall combining losses are
only in the 0.2 to 0.5 dB range.

Figure 1-3 shows the effects of phase imbalance on the power combining efficiency.

intervention is required unless an amplifier or other critical system component,

The following paragraphs are provided for informational purposes only.

See Chapter 3. OPERATION and ADJUSTMENT PROCEDURES for
operational and alignment information.

Naturally, two separate amplifiers are likely to have different phase and gain characteristics. The
PCB-4000A 1+1 system is designed such that the phase difference between the two amplifier
paths is compensated by adjusting the phase shifter in the PCCB. This is done at the factory for
the full amplifier bandwidth, and should not normally require further adjustment in the field unless
an amplifier has been replaced.

Introduction 1–4 MN-PCB-4000A

PCB-4000A 1+1 Phase Combiner
Revision 2

1.3.2 System Gain

The gains of the amplifiers are calibrated at the factory to provide optimum system performance.
The amplifier gain difference is automatically compensated for by the PCCB M&C System. Upon
power up, the M&C reads the gain of each individual amplifier as calibrated at the factory, and
automatically attenuates the amplifier with the most gain so as to be equal with the lower gain
unit.

For example, if SSPA #1 had a factory-calibrated gain setting of 76 dB, and SSPA #2 had a
factory-calibrated gain setting of 73 dB, the M&C system would automatically set the attenuation
setting of SSPA#1 to 3 dB to equalize the system gain. Although not gen er ally needed or
recommended, a user input gain offset setting is also provided for system fine-tuning.

See Chapter 3. OPERATION and ADJUSTMENT PROCEDURES for
operational and alignment information.

Due to the power divider and cable losses, the overall gain of the system will be less than the
individual gain of each amplifier. Please refer to the system test data sheet for actual system
gain.

1.3.3 System Attenuation

The PCB-4000A makes it easy to adjust the overall system gain. Upon input of the requested
attenuation setting, the PCB-4000A automatically adjusts the gain of each SSPA accordingly,
resulting in the desired attenuation value while maintaining optimum power combining conditions.

The SSPAs included in the system are calibrated over a range 10 dB beyond specification (30 dB
vs. 20 dB). As explained above, a portion of the 30 dB range is required for gain equalization.
Therefore, the maximum allowable attenuation in a 1+1 system is software limited to 24 dB, but
still exceeds system specifications.

1.3.4 Soft Fail Protection

In the event of a failure of one of the SSPAs, the PCB-4000A controls the waveguide switches
such that the good unit’s power is routed around the “Magic-Tee” combiner directly to the output
port. This results in only a 3 dB power loss, or “soft failure”. Without the waveguide switches, a
failure in one unit would result in a 6 dB power loss.

2.5 Power and Ground Interfaces

2.5.1 AC Pow er

The PCB-4000A derives its power from the SSPAs. Each SSPA provides a +24V signal line via
cables interconnecting the SSPAs to the SSPA COM 1 | J2 and SSPA COM 2 | J3 connectors
(Pin ‘R’ – see Table 2-3). These two signals are “diode OR’ed” to provide redundancy.

Although the PCCB will turn on and function with only one SSPA is powered on,
the system does not provide optimum output power unless both SSPAs are
powered on.

3.1 Overview

Chapter 1. INTRODUCTION

As indicated in Chapter 1. INTRODUCTION, the PCB-4000A 1+1 Phase Combiner system is
aligned at the factory using a network analyzer. The in-factory adjustments are based on the
specific arrangement of the SSPAs within the system. To ensure proper system operation and
performance, it is mandatory that the components are installed in the same positions as was
done in the factory. See Figure 3-1 for an assembly example.

Although the techniques featured in this chapter afford easy adjustment and setting of the phase
shifter for optimum output power combining over the full amplifier bandwidth, alignment in the

field is generally not required and it is strongly cautioned against making unneeded
adjustments.

However, if an amplifier or other critical system component is replaced (e.g., the PCB-4000A
unit), the procedures provided in this chapter explain the steps necessary to restore proper
system operation. This chapter also provides a verification procedure in the event that proper
system operation confirmation is required.

It is recommended that only qualified personnel familiar with high-power
amplifiers, test equipment, and phase combined systems attempt these
procedures.

output port is terminated in a broadband high power load as depicted in Figure 1-2 block diagram
in Chapter 1. INTRODUCTION. If the system is “live” and you desire only to verify operation, see
Section 3.5.

Verify the overall system performance by measuring the ratio of the transmitted power to that of
the power being dissipated by the “dummy” load. Adjust the gain and amplitude balance if
necessary.

Follow these steps:

SSPA#2 will be sent to the system output, while SSPA#1 will be muted and directed to the “wasted” port.

Compare the levels of the two paths. Typically, the gains of each SSPA will be within ± 1 dB at center

3.4 Gain or Amplitude Balance Verification and Alignment

This procedure is generally not necessary if all parameters of Section 3.3
have been met.

As a result of the configuration of the waveguide switches in a 1+1 system, it is possible to
measure the individual gain of each SSPA path by switching each SSPA individually to the output
load.

This procedure assumes that the output port is terminated and that data will be taken using the

B. Apply a low-level signal at center frequency, making sure the output signal (at the system output port –

not the coupled port) will be at least 10 dB below Prated.

If the Wasted (“Load”) power level is 15-20 dB below the transmitted power, the system is operating correctly.
However, if the ratio is below 10-15 dB, proceed to the align the phase shifter:

Verify that the system works over the full bandwidth by injecting a signal at the start and stop frequencies as

performance at any one particular frequency must be sacrificed slightly to achieve full bandwidth operation.

3.6 Phase A lignment

As the system is aligned at the factory, this step is typically not required
unless it is necessary to replace one of the SSPAs or other critical path
components. Make sure to meet all parameters of Section 0 before performing
this adjustment.

This procedure assumes that the system installation is complete and that the output port
terminates in a broadband high power load.

Verify the overall s ystem performance b y measuring the ratio of the transmitted po wer to that of
the power being dissipated by the “dummy” load. If necessary, adjust the phase balance by

hyperlink.

f. Select the appropriate firmware archive EXE or ZIP file download hyperlink.

• About Firmware Numbers, File Versions, and Formats: The Comtech
EF Data Web site catalogues its firmware update files by product type
(e.g., router, modem, etc.), the specific model, and optional hardware
configurations.

The download hyperlink for the PCB-4000A base unit firmware appears as
FW-0021045x.zip, where ‘x’ denotes the revision letter.

• About File Archive Formats: Comtech EF Data provides its
downloadable files in two compressed archive formats: *.exe (self­extracting) and *.zip (compressed).

The *.exe file does not require a file archiver and compression utility
program such as PKZIP for Windows, WinZip, ZipCentral, etc. (PKZIP for
DOS is not supported due to file naming conventions). Comtech EF Data

does not provide this utility program.

Some firewalls do not allow the download of *.exe files. Download the *.zip
file instead, and extract the firmware files from the archive download with a
user-supplied utility program. For detailed information on handling archived
files, refer to the utility program Help documentation.

g. Download the firmware archive file to the temporary folder.

• Once the EXE or ZIP hyperlink is selected the ‘File Download’ window opens and
prompts selection of [Open] or [Save]:

o Click [Open] to turn over file extraction to the user-supplied utility program . Be

sure to extract the firmware files to the “temp” folder created earlier.

o Click [Save] to open the ‘Save As’ window. Be sure to select and [Save] the

Chapter 5. SERIAL REMOTE CONTROL

5.1 Overview

Remote monitor and control of the PCB-4000A 1+1 Phase Combiner is available only through an EIA-232 connection, and data is
transmitted in asynchronous serial form using ASCII characters. Control and status information is transmitted in packets of variable length,
in accordance with the structure and protocol defined in later sections.

5.1.1 EIA-232

The Controller device connects directly to the Target via a two-wire-plus-ground connection. Controller-to-Target data is carried, via
EIA-232 electrical levels, on one conductor, and Target-to-Controller data is carried in the other direction on the other conductor.

PCB-4000A 1+1 Phase Combiner
Revision 2

Serial Remote Control 5–2 MN-PCB-4000A

5.2 Remote Command s a nd Q ue ri es Ovierview

5.2.1 Basic Protocol

All data is transmitted as asynchronous serial characters, suitable for transmission and reception by a UART. The asynchronous character
is fixed at 8-N-1 (8 data bits, no parity, one stop bit). Only two baud rates are supported: 9600 baud and 19200 baud.

All data is transmitted in framed packets. The host Controller is assumed to be a user PC running a terminal emulator program or an
ASCII dumb terminal that is in charge of the process of monitor and control. The Controller is the only device that is permitted to initiate, at
will, the transmission of data. Targets are only permitted to transmit when they have been specifically instructed to do so by the Control ler.

All bytes within a packet are printable ASCII characters, less than ASCII code 127. In this context, the Carriage Return and Line Feed
characters are considered printable.

All messages from Controller-to-Target require a response – with one exception: This will be either to return data that has been requested by the
Controller, or to acknowledge reception of an instruction to change the configurati on of the Target.

• Controller-to-Target – This is the character ‘<’ (ASCII code 60).

• Target-to-Controller – This is the character ‘>’ (ASCII code 62).

Because this is used to provide a reliable indication of the start of packet, these two characters may not appear anywhere else within the
body of the message.

PCB-4000A 1+1 Phase Combiner
Revision 2

Serial Remote Control 5–4 MN-PCB-4000A

5.2.2.2 Target (Base) A ddress

Up to 9,999 devices can be uniquely addressed. In the EIA-232 application, the permissible range of values is 1 to 9999. It is programmed
into a Target unit using serial remote control. The factory default target address is 1.

The Controller sends a packet with the address of a Target – the destination of the packet. When the Target responds,
the address used is the same address, to indicate to the Controller the source of the packet. The Controller does not
have its own address.

5.2.2.3 Virtual Address

Virtual Address is a method th at allows t he user to ac cess the SSPA via the PCC B using any communic ations softwar e. Virtual Address is
supported in the EIA-232 application.

The following example depicts use of the virtual addressing scheme:

<123V1/MUT? where:

Base address = 123;
‘V’ = virtual address delimiter;
1 = virtual address of SSPA automatically set by the PCCB.

Notes:

1. Only four virtual commands can be used to program the individual SSPAs when in Phase Combined mode (RED=1):

• CAA=

• DAT=

• TIM=

• IAP=

2. All virtual queries can be directed to the individual SS PAs in any mode.

3. The following virtual commands can NEVER be used to program the individual SSPAs:

• MUT=

• ATT=

Serial Remote Control 5–5 MN-PCB-4000A

5.2.2.4 Address Delimiter

This is the “forward slash” character '/' (ASCII code 47).

5.2.2.5 Instruction Code

This three-character alphabetic sequence identifies the subject of the message. Wherever possible, the instruction codes have been
chosen to have some significance. This aids in the readability of the message if seen in its raw ASCII form. Upper and lower case
alphabetic characters (i.e., A-Z [ASCII codes 65-90], and a-z [ASCII codes 97-122]) may be used.

5.2.3 Instruction Code Qual ifie r

This single character further qualifies the preceding instruction code.
Code Qualifiers obey the following rules:

1. From Controller-to-Target, the only permitted values are:

Symbol

Definition

=
(ASCII code 61)

‘=’ is used as the assignment operator, and is used to indicate that the parameter defined by the preceding byte should be set to the

value of the argument(s) that follow it. For example: MUT=1 would mean 'enable the Mute function.'

?
(ASCII code 63)

‘?’ is used as the query operator, and is used to indicate that the Target should return the current value of the parameter defined by

the preceding byte. For example: MUT? Would mean ‘return the current state of the Mute function.’

2. From Target-to-Controller, the only permitted values are:

Symbol

Definition

=

(ASCII code 61)

The = code is used in two ways:
First, if the Controller has sent a query code to a Target (for example: MUT? would mean ‘return the current state of the Mute

function’), the Target would then respond with MUT=x, where ‘x’ represents the state in question (1 being ‘enabled’, 2 being ‘disabled).
Second, if the Controller sends an instruction to set a parameter to a particular value, then, providing the value sent in the argument is

valid, the Target will acknowledge the message by replying with MUT= (with no message arguments).

PCB-4000A 1+1 Phase Combiner
Revision 2

Serial Remote Control 5–6 MN-PCB-4000A

Symbol

Definition

?

(ASCII code 63)

The ? code is only used as follows:
If the Controller sends an instruction to set a parameter to a particular value, then, if the value sent in the argument is not valid, the

Target will acknowledge the message by replying (for example) with MUT? (with no me ssage arguments). This indicates that there was
an error in the argument of the message sent by the Controller.

!

(ASCII code 33)

The ! code is only used as follows:
If the Controller sends an instruction code that the Target does not recognize, the Target will acknowledge the message by echoing the

invalid instruction, followed by the ! character; for example, XYZ!

*

(ASCII code 42)

The * code is only used as follows:
If the Controller sends an instruction to set a parameter to a particular value, but then the value sent in the argument is valid but the

target is in the wrong mode (e.g., Standby mode in Redundancy configuration or the Remote state is Ethernet Remote (LRS=3)), such
that it will not permit that particular parameter to be changed at that time, the Target will acknowledge the message by replying ( for
example) with MUT* (with no message arguments).

#

ASCI code 35)

The # code is only used as follows:
If the controller sends an instruction code that the target cannot currently perform because of hardware resource issues, then the target

will acknowledge the message by echoing the invalid instruction, followed by the # character; for example, MUT# (with no message
arguments).

5.2.4 Optional Message Arguments

Arguments are not required for all messages. Arguments are ASCII codes for the characters 0 to 9 (ASCII codes 48 to 57), period (ASCII
code 46) and comma (ASCII code 44).

5.2.5 End of Packet

• Controller-to-Target – This is the ‘Carriage Return’ character (ASCII code 13).

• Target-to-Controller – This is the two-character sequence ‘Carriage Return’, ‘Line Feed’ (ASCII codes 13 and 10).

Both indicate the valid termination of a packet.

REMOTE PRODUCT

MANAGEMENT

6.1 Overview

Ethernet-based Remote Product Management is available using the SYSTEM COM | J1
connector.

THAT:

• The PCB-4000A is operating with the latest version firmware files.

• The PCB-4000A is connected to a user-supplied, Windows-based PC, and:

o The PC Ethernet port is connected to the PCB-4000A SYSTEM COM | J1

6.2 Ethernet Management Interface Protocols

The user PC facilitates access to Ethernet-based remote monitor and control (M&C) of the
PCB-4000A through the Simple Network Management Protocol (SNMP). This non-secure
interface requires a user-supplied Network Management System (NMS) and a user-supplied
Management Information Base (MIB) File Browser.

SNMP user interface is only available when the unit’s Local/Remote state is set to Ethernet
Remote through LRS serial remote command (LRS=3).

6.3 SNMP Interface

The SNMP is an Internet-standard protocol for managing devices on IP networks. An SNMP
managed network consists of three key components:

• The managed device. This includes the PCB-4000A.

• The SNMP Agent. The software that runs on the PCB-4000A. The SNMP Agent

supports both SNMPv1 and SNMPv2c.

• The user-supplied NMS. The software that runs on the manager.

Revision 2

6.3.1 Management Information Base (MIB) Files

MIB files are used for SNMP remote management of a unique device. A MIB file consists of a tree
of nodes called Object Identifiers (OIDs). Each OID provides remote management of a particular
function. These MIB files should be compiled in a user-supplied MIB Browser or SNMP Network
Monitoring System server. The following MIB files are associated with the PCB-4000A:

Table 6-1. Management Information Base Files

Description

ComtechEFData MIB file

and consists of only the following OID:

Name: comtechEFData
Type: MODULE-IDENTITY
OID: 1.3.6.1.4.1.6247
Full path:

iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).comtechEFData(6247)

MIB file consists of all of the OIDs for management of the unit functions.

MIB file consists of all of the OIDs for traps of the unit functions.

6.3.2 SNMP Community Strings

the SNMP packets. Caution must be taken by the network administrator to
ensure that SNMP packets travel only over a secure and private network if

The PCB-4000A uses Community Strings as a password scheme that provides authentication
before gaining access to the Agent MIBs. They are used to authenticate users and determine
access privileges to the SNMP Agent.

Type the SNMP Community String into the us er -supplied MIB Browser or Network Node
Management software.

Two Comm unit y Strings are defined for SNMP access:

• Read Community default = public

• Write Community default = private

The Read and Write Community Strings can be conf igured using serial remote comm and RCM
and WCM when remote state is at Serial Remote.

For proper SNMP operation, the PCB-4000A MIB files must be used with the
associated version of the unit. Refer to the PCB-4000A FW Release Notes for
