Section 1.4.4 Power Supply
The LPOD-R features a power supply that is power factor corrected. It supplies several voltages
necessary for the unit to operate:
• The 10V power supply output state is controlled by circuitry within the RF module. If the RF
module does not have the –5.8V supply for any reason, i t will not allow the 10V power supply to
turn on. This protects the power transistors within the RF module from failure due to improper
power supply sequencing.
• The +24V output powers the cooling fans and is the source of power for waveguide switching
when the SSPA is used in redundant configurations.
• The +5.8V, -5.8V, +7.8V and +13.5V outputs are used to operate the M&C board and other
overhead functions.

Preface Revision 3
• 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.
While the LPOD-Rdoes 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-Rprovides a grounding terminal. This is provided
to allow you to ground the LPOD-R 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-Rexcept 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-R family of Outdoor Amplifiers / Block Up Converters
(BUCs) – referred to collectively throughout this manual as the LPOD-R – deliver
their rated power, guaranteed, to the transmit waveguide flange at the 1 dB
compression point. The LPOD-R provides a cost effective to the LPOD, where the
full LPOD-R’s support of internal 10 M Hz and redundancy is not required.
Figure 1-1. Comtech EF Data LPOD-R Outdoor Amplifiers / BUCs
1.2 Functional Description
The LPOD-R serves as a more reliable replacement for Traveling Wave Tube
(TWT) amplifiers in satellite communications. The compact size and weight of the
LPOD-R 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.
As shown in Figure 1-1, Comtech EF Data’s LPOD-R is available in three models:
the PS .5, the PS 1, and the PS 1.5. Each LPOD-R consists of a CEFD SSPA module
1–1
LPOD-R Outdoor Amplifier / Block Up Converter (BUC) MN-LPODR
Introduction Revision 3
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
MCP-based temperature-versus-gain compensation.
1.3 Features
1.3.1 The Solid-State Advantage
The LPOD-R 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-R’s rated output. The LPOD-Rs also provide mean
time between failures (MTBF) that is four to five times greater than the typical
TWT MTBF.
1.3.2 “Smart BUC” Functionality
The LPOD-R offers full 13.75 to 14.5 GHz Ku-Band and 5850 to 6725 MHz C-Band
coverage while supporting industry standard FSK modem/BUC communications,
as well as Comtech EF Data proprietary commands.
1.3.3 Enhanced Standard Features
The LPOD-R comes equipped with useful features that other manufacturers offer
only as options. Included in the base price are temperature compensation, power
monitor, power factor corrected supply, and full remote monitor and control
(M&C) capabilities (including Ethernet, FSK, and Comtech’s proprietary Advanced FSK).
1.3.3.1 Advanced FSK
The LPOD-R, when used with Comtech EF Data modems, provides enhanced
functionality utilizing the industry standard FSK communications channel.
Advanced FSK offers full control of single thread and, where applicable,
redundant systems from the modem front panel, without additional cabling or
cost. Additionally, access the LPOD-R via the Ethernet M&C port of the modem,
and control it via Embedded Distant-end Monitor and Control (EDMAC).

Introduction Revision 3
1.3.3.2 Data Logging Capability
To enhance system maintainability, the LPOD-R includes a built-in data logging
capability. By recording critical operational parameters such as temperature,
output power, mute status, etc. at time stamped intervals, you can quickly
gather intelligence about not only the unit itself but also the unit’s operational
environment.
1.3.3.3 Hand-Held Controller Devices
The LPOD-R accommodates a variety of hand-held controller devices. These
include the LPODnet M&C Accessory Kit and the CLC-10 M&C Accessory Kit. Both
are designed to access the monitor and control functionality of the LPOD-R.
1.4 Theory of Operation
1.4.1 SSPA Block Diagrams
See Figure 1-2 for a typical LPOD-R block diagram.
The major components of an LPOD-R unit are:
• The SSPA Module
• The Cooling system
• The Power Factor Corrected Power Supply (PS 1 and PS 1.5 units)
• Monitor & Control (M&C)

1.4.2 SSPA Module
The amplifier module performs the core function of the unit. An isolator is at the
RF input to ensure good voltage standing wave ratio (VSWR). The RF signal then
passes through an electronically controlled attenuator that adjusts the overall
attenuation according to the user input. After some amplification, a second
attenuator is automatically controlled via a look-up table to maintain the
amplifier gain at a constant level over temperature variations.
The RF signal is then amplified by a multi-stage design that utilizes proprietary
combining techniques to meet the rated power requirements. The output
circuitry contains a coupler to provide a sampled signal for monitoring purposes.
A power detector circuit also is included and the reading can be accessed via
remote communication. A high power circulator and load is located at the output
to provide good VSWR and protection from external mismatch.

Introduction Revision 3
1.4.3 Cooling System
• The PS .5 contains a single fan that is always enabled.
• The PS 1 contains one temperature-controlled fan.
• The PS 1.5 contains two temperature-controlled fans.
1.4.4 Power Supply
The LPOD-R features a power supply that is power factor corrected. It supplies
several voltages necessary for the unit to operate:
• The 10V power supply output state is controlled by circuitry within the RF
module. If the RF module does not have the –5.8V supply for any reason,
it will not allow the 10V power supply to turn on. This protects the power
transistors within the RF module from failure due to improper power
supply sequencing.
• The +24V output powers the cooling fans, is the source of power for
waveguide switching when the SSPA is used in redundant configurations,
and is dropped to +22V for LNB bias.
• The +5.8V, -5.8V, +7.8V and +13.5V outputs are used to operate the M&C
board and other overhead functions.
1.4.5 Block Up Converter (BUC) Input
The LPOD-R translates an L-Band input carrier to the desired output frequency
(C-, X-, or Ku-Band). LO frequencies are as follows:
BUC C-, X-, Ku-Band LO Frequencies
Band Frequency LO Frequency Inverting
C-Band
Insat C-Band 6725 to 7025 MHz 5760 MHz No
Ku-Band 14.00 to 14.50 GHz 13.050 GHz No

Introduction Revision 3
1.4.6 Monitor and Control (M&C)
The LPOD-R includes a microprocessor-based system that provides monitoring
and control of the essential parameters of the unit. You interface with the unit
through the M&C system via the remote control/discrete communications port.
The unit is capable of Ethernet remote communication, while EIA-232/485 is
optional on the PS 1 and PS 1.5 packages. A discrete mute control and relay
status output is also available on the PS 1 and PS 1.5 packages.
The M&C system monitors the fan speed, unit temperature, all power supply
voltages, power transistor currents, output power, etc. Should a critical
monitored parameter fail, the unit will mute the RF signal and report a fault. The
details of the fault can be accessed via remote communication.
The LPOD-R PS .5 features a Light-Emitting Diode (LED) Indicator. Figure 1-3
shows the location of this feature, on the signal output side of the LPOD-R PS .5
housing, next to the ground lug. This LED provides you with visual cues to the
operational, online, and offline status of the system. See Chapter 2 for complete
details about interpreting LED operation.
