Ku-Band ODPA High Power Outdoor Power Amplifier
Using components from Comtech EF Data's proven line of Ku-band
transceivers, this 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. The SSPA portion is line
powered and provides an analog interface for fault status and mute
The ODPA delivers up to 50 Watts, at the 1 dB compression point (60W
Psat), 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-topoint links.

The Solid State Advantage
The ODPA is constructed with highly reliable GaAs FETs. With
third-order intermodulation products from 4 to 6 dB better than TWT
ratings, the Comtech EF Data unit will replace TWTs with saturated
power levels of up to twice the ODPA's rated power. The ODPA provides
an MTBF that is 5 to 6 times greater than the typical TWT MTBFs.
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.
