Electrical Safety and Compliance
CAUTION
NEUTRAL FUSING – DOUBLE POLE/NEUTRAL FUSING IS USED ON THE PRIME
This equipment has been designed to minimize exposure of personnel to
hazards. For further information, contact Comtech EF Data Product Support. The
operators and technicians must:
• Know how to work around, with, and on high voltage equipment.
• Exercise every precaution to ensure personnel safety.
• Exercise extreme care when working near high voltages.
• Be familiar with the warnings presented in this manual.
Installation Guidelines Regarding Power Line Quality
Comtech EF Data has become familiar with the varying quality of the AC power
grid around the world. Observing the following installation guidelines should
help ensure a reliable installation.
• Surge suppression – High voltage surges can cause failure of the power
supply. These surges are typically caused by circuit switching on the main
AC power grid, erratic generator operation, and also by lightning strikes.
xvii
LPOD C-, X-, or Ku-Band Outdoor Amplifier / Block Up Converter (BUC) MN-LPOD
Preface Revision 14
While the LPOD does have built in surge suppression, if the unit is to be
installed in a location with questionable power grid quality, Comtech EF
Data recommends installation of additional power conditioning/surge
suppression at the power junction box.
• Grounding – The LPOD provides a grounding terminal. This is provided to
allow you to ground the LPOD to the antenna’s grounding network. All
components installed at the antenna should be grounded to a common
grounding point at the antenna.
• Electrical welding – If welding needs to take place at the antenna,
disconnect all cables from the LPOD except for the ground wire. Cap all
RF connections with terminations. This will prevent damage to the
input/output circuitry of the LPOD.
• Lightning – Lightning strikes on or around the antenna will generate
extremely high voltages on all cables connected to the LPOD. Depending
on the severity of the strike, the LPOD’s internal surge protection
combined with the recommended external suppression may protect the
LPOD’s power supply. However, if the installation will be in an area with a
high probability of lightning strikes, Comtech EF Data recommends the
installation of surge suppression on the RF and IF cables. One source of
these suppressors is PolyPhaser (www.polyphaser.com).

Chapter 1. INTRODUCTION
1.1 Overview
Comtech EF Data’s LPOD family of Outdoor Amplifiers / Block Up Converters
(BUCs) – referred to collectively throughout this manual as the LPOD – deliver
their rated power, guaranteed, to the transmit waveguide flange at the 1 dB
compression point. The LPOD provides a cost effective, more reliable
replacement for Traveling Wave Tube (TWT) amplifiers in satellite
communications.
Comtech EF Data’s extensive experience in the design of outdoor RF transceivers
led to the LPOD family’s efficient thermal and mechanical package. Recognizing
the evolution of L-Band IF systems, the LPOD is designed to eliminate the
traditional requirement for the modem to supply a DC power source and a 10
MHz reference to the BUCs and LNBs.

Introduction Revision 14
1.2 Functional Description
The compact size and weight of the LPOD lends itself to any installation with
limited available mounting space. These include ship-borne antenna systems,
small “flyaway” systems, and Satellite News Gathering (SNG) installations. The
addition of the optional internal reference and LNB bias T facilitates multi-carrier
and redundant operations required of small-to medium-sized hub installations.
As shown in Figure 1-1, Comtech EF Data’s LPOD is available in three models: the
PS 1, PS 1.5 and PS 2. Each LPOD consists of a CEFD SSPA module with the
Monitor/Control Processor (MCP), a power supply, and a fan assembly. The
amplifier features a Comtech EF Data low loss combining technique and MCPbased temperature-versus-gain compensation.
The PS 1 and PS 1.5 models are always configured as a BUC/SSPA (L-Band in, RF
out) with available power levels to 100W; the PS 2 version can be configured as
an integrated BUC/SSPA or solely as an SSPA (RF in, RF out) at power levels to
250W.
1.3 Features
1.3.1 The Solid-State Advantage
The LPOD is constructed with highly reliable gallium arsenide field-effect
transistors (GaAs FETs). With third-order intermodulation products that are 4 to 6
dB better than TWT ratings, the CEFD unit replaces TWTs with saturated power
levels of up to twice the LPOD’s rated output. The LPODs also provide mean time
between failures (MTBF) that is four to five times greater than the typical TWT
MT BF.
1.3.2 Enhanced Standard Features
The LPOD comes equipped with useful features that other manufacturers offer
only as options. Included in the base price are temperature compensation,
sample ports (on the PS 2 only), power monitor, power factor corrected supply,
1–2

Introduction Revision 14
and full remote monitor and control (M&C) capabilities (including Ethernet and
serial).
1.3.3 Built-in Redundancy Controller
The LPOD has the ability to function as a 1:1 (one backup for one primary)
redundant controller in a redundant mode without the use of an external device.
The optional redundancy configuration is implemented by attaching a ganged
waveguide/coax transfer switch(es) to the input and output connectors of the
amplifiers, using a combination coaxial cable and waveguide kit.
When the backup LPOD is commanded into redundant mode, it monitors the
online LPOD for faults and status, and automatically maintains a configuration
based on the online unit.
A faulted online unit may be disconnected and replaced without affecting the online
power amplifier.
1.3.4 “Smart BUC” Functionality
Comtech EF Data’s unique approach to L-Band/RF frequency conversions
eliminates DC and 10 MHz from the input coax. This simplifies redundant and
multi-carrier operation. Full 13.75 to 14.5 GHz Ku coverage and 5850 to 6725
MHz C band coverage is offered while supporting industry standard FSK
modem/BUC communications, as well as Comtech EF Data proprietary
commands.
Both LPOD models have a self-contained power supply, eliminating the
requirement for the modem to supply the BUC voltage on the center conductor
of the RF cable, simplifying multi-carrier operation and modem spares
maintenance.
1.3.5 Data Logging Capability
To greatly enhance system maintainability, the LPOD includes a built-in data
logging capability. By recording critical operational parameters (such as
temperature, output power, mute status, etc.) at time stamped intervals, the
1–3

Introduction Revision 14
user can quickly gather intelligence not only about the unit itself, but also the
unit’s operational environment.
1.3.6 Optional Internal 10 MHz Reference
With the optional high stability, oven-controlled crystal oscillator (OCXO)
installed, one more signal is removed from the TX IF cable. This ensures optimum
RF performance of the BUC by eliminating any reference degradation caused by
IF combiners, interconnections, or rotary joints.
1.3.7 Optional LNB Support
The LPOD was designed with the evolution of L-band systems in mind. L-band IF
topologies are no longer relegated to low power single carrier installations, and
are now found in larger multi-carrier installations. A challenge presented by
multi-carrier L-band systems is the presence of DC and reference components on
the Tx/Rx L-band interfaces. The LPOD design, by default, eliminates the DC
component from the Tx IF and can eliminate the reference requirement with the
optional internal OCXO. The LNB bias/reference option completes the solution by
eliminating DC and reference signal requirements from the Rx L-band interface.
