Model number TR 0.020-0.800-50 is a high power, transmit/receive (TR) module that operates from 20 to 800 MHz minimum and is packaged in a rugged enclosure. This TR module is employed in electronic warfare systems or communication systems where high power, decent linearity and high efficiency are required. This module is designed and manufactured for operation in extremely harsh environments. Typical output power is 40 to 50W across the band at P3dB. Small signal gain is -50 dB typical. Nominal input power is 0 dBm but any input power range can be amplified as this module offers a very large dynamic range. Input VSWR is 2.0:1 maximum. The receive function in this module is passive and offers a typical loss between 1 to 2 dB. Tx/Rx and Rx/Tx switching times are 2uSecs maximum. Tx/Rx isolation is -60 dB typical. There is a limiter in the Rx path to limit the power downstream. Average module efficiency is -50% across the band. Standard features include reverse polarity protection, output short and open circuit protection, and over/under voltage protection. Temperature is monitored and reported by the module.
