Aethercomm Model Number TR 0.24-0.39-75 is a high power, RF transmit/receive system that operates from 290 MHz to 390 MHz minimum and is packaged in a compact, rugged enclosure. This TR module transmits from 290 to 390 MHz with an output power of 100 watts typical. Receive frequencies are 240 to 270 MHz and this RF module offers 3.0 dB of noise figure with ~ 18 dB of gain. This transmit assembly is designed and manufactured for operation in harsh environments where communication systems are deployed. The design offers high power added efficiency in Tx mode. Nominal input power is 2.0 watts but any input power range can be amplified as this module offers a very large dynamic range. Input and output VSWR is 2.0:1 maximum. This unit is equipped with DC switching circuitry that enables and disables the Tx and Rx functions in less than 10uSecs. Standard features include reverse polarity protection and output short and open circuit protection. This RF transmit amplifier operates from a +18 to +36 Vdc power supply. This TR Module operates from -40C to +71C base plate temperature. The system is operated in both pulsed and CW modes.
