High-Power Transmit/Receive Module: P/N TR 1.35-1.45-20 -- Datasheet

This High Power Transmit/Receive Module operates in transmit or receive mode at any given time but not simultaneously. Typical transmit duty cycles do not exceed 50%. In Rx mode, the module provides a low noise front-end that includes band limited filtering, a high power limiter, low-noise amplification and image rejection filtering. In the Tx mode, the module amplifies a low level, L Band signal up to a power level of greater than 20 watts at the antenna. The antennal port offers a bi-directional interface to the Rx and Tx sections of the module. This unit is fully GPS compliant. Standard features include forward power monitoring, reflected power monitoring, output short and open circuit protection, over and under voltage protection, receiver protection, very fast switching speeds between Rx and Tx operation and a fully regulated DC-DC converter. This unit operates from +28Vdc, -28Vdc and +10Vdc power supplies and can survive temperatures of 95C base plate before the unit shuts off with over- temperature protection. This high performance module is enclosed in a very compact 4.0" by 8.0" by 1.7". It is environmentally sealed and can be withstand immersion in water.

Features:

• High power, L band transmit/receive module
• Tx minimum output power = 20 watts @ 25C
• Rx typical noise figure = 2.0 dB
• Fully GPS compatible
