Chapter 1. Introduction

1.1 Description

The Ku-Band Outdoor Power Amplifier (ODPA) provides higher output power than
typically available in a block package. The optional L-Band Up Converter requires 24
VDC and a 10 MHz reference on the coax from an L-band modem.

Figure 1-1. 25-40 Watt High Power Ku-Band BUC

1–1

Outdoor Power Amplifier Revision 0
Introduction MN/ODPA.OM

The SSPA portion is line powered and provides an analog interface for fault status and
mute control.

The ODPA delivers up to 40 Watts, at the 1 dB compression point, to the transmit
waveguide flange. It provides a cost-effective and reliable replacement for TWT
amplifiers in Ku-Band terminals. Due to a small form factor, it is ideal for the
construction of small “flyaway” terminals, Intelsat earth stations, and hub earth stations
for small- to medium-size private networks or point-to-point links.

1.3 Functional Description

The ODPA consists of a chassis, power supply, fan assembly, Monitor and Control
Processor (MCP) and a Comtech EF Data SSPA module. The amplifier is designed using

a Comtech EF Data low loss combining technique and an MCP based temperature versus
gain compensation.

1. Position the two 20” Unistrut channels on the backside of the BUC box, aligning
and centering the two center slots of the channel with the mounting holes of the
BUC. Fasten with the 1/4” hardware (4 each bolts, split and flat washers).

2. Position the BUCs and mounting brackets facing upward, leaving a gap between
roughly the width of the BUC. Ensure that all items are oriented correctly and
fasten with the 1/4” hardware (twelve each bolts, split and flat washers).

Note: It may be necessary to loosen the hardware on the BUC in order to align
the mounting holes between the Unistrut channels and the converter brackets.

3. (For SPAR Mount Kit PL/7725-1 only) Using a Spar support bracket as a guide,
position two spring nuts in each of the Unistrut channels. The threaded holes in
the spring nuts must be aligned with the holes in the Spar support brackets and
should be centered in the Unistrut channels.

4. (For Spar Mount Kit PL/7725-1 only) Position the assembly on the Spar arm of
the antenna and fasten the Spar support brackets to the spring nuts in the
Unistrut with the 5/16” hardware (4 each bolt, split and flat washer).

5. Ensure that the assembly is mounted in such a manner as to provide enough
room for cabling and to avoid interference to surrounding objects.

2.3.2 BUC Round Pole Mounting Instructions

1. Position the BUC and mounting brackets facing upward. Position (2) 14”
Unistrut channels centered on the converter mounting brackets. Fasten with
hardware (4 to 6 each of bolts, split and flat washers).

Note: Vary the number and location of the hardware as needed to avoid
interfering with the spring nuts used for the pipe blocks.

2. Position two spring nuts into the channel of one of the remaining Unistrut
channels. With the mounting holes facing the ends of the channel, fasten two
pipe blocks loosely to the spring nuts with the hardware

(2 each 5/16” bolts, split

and flat washers).

3. Place the channel with pipe blocks against the mounting pole, slide the pipe
blocks until they contact the mounting pole. Ensure the pipe blocks are centered
to the Unistrut and tighten the hardware. Use this channel as a guide and mount
the pipe blocks on the remaining three channels in a similar manner.

4. Position two spring nuts in each of the Unistrut channels mounted to the BUC.
Position these nuts between the pipe blocks and the ends of the Unistrut.

Note: Above the spring nuts, position the flat fitting plates with the locating
notches engaged in the openings of the channels.

5. Thread a 5/16” nut, split and flat washer onto each of the threaded rods, leaving
1” of rod remaining. Thread that end of the rod through the flat fitting plates and
fully into the spring nuts (do not bottom out). Using one of the mating channels,
ensure that the threaded rods from the channels mounted to the BUCs are
aligned with holes in the mating channels. Center these rods with the channels as
well as possible and tighten the hardware.

6. Thread a 5/16” nut, split, flat washer and flat fitting plate on the remaining ends
of the threaded rods. This hardware is to secure the mating Unistrut channels
from the opposite side of the pole to the threaded rod. Adjust accordingly.

7. Position the BUC with the pipe blocks against the pole, slide the mating Unistrut
channels onto the threaded rods from the opposite side (pipe blocks against pole
and channels against flat fitting plates). Adjust and fasten with the

5/16”

hardware (4 each flat, split washers, and nuts).

parameters, such as:

• RF Mute: On/Off => Turn the Ku-Band SSPA On/Off

• SSPA Fault Monitor

Remarks

Control / Monitor Pin:
For control, pull pin to GND to mute, unit
has an internal pull-up resistor.
For Monitor, pin will be pulled to GND by
the SSPA’s M&C if a fault is present.

High Power Ku-Band BUC Revision 0
Operation MN/HPAKUBUC.OM

3.3 Theory of Operation

The ODPA is required to have a 10 MHz reference signal, and a +15 to 24 VDC supply
voltage from an L-Band Modem to the N-Type female connector (J3).

The ODPA will lock to the 10 MHz reference and then up convert an L-Band input signal
to the Ku-Band output frequency. It outputs this low level signal on Ku-Band OUT (J4).

The Ku-Band output from L-Band to Ku-Band BUC will feed to the RF Input (J1). The
SSPA will amplify the input Ku-Band signal from the BUC up to the desired output level.
