TR61 Image

The TR61 from Communications and Power Industries is an X-Band GaN Transceiver with a Tx frequency from 7.9 to 8.4 GHz and an Rx frequency from 7.25 to 7.75 GHz. It is based on a fully integrated solution that combines an orthomode transducer (OMT), Tx filter, GaN power amplifier, block-up converter (BUC), Rx filter, Tx/Rx local oscillators, low noise block (LNB), power supply, and other control components in a small, lightweight package. On the Tx side, this transceiver up-converts an input frequency from 950 to 1450 MHz to 7.9 to 8.4 GHz with a small signal gain of over 60 dB and an SSB phase noise of -112 dBc/Hz (10 MHz offset). On the Rx side, it down-converts a frequency from 7.25 to 7.75 GHz to 950 to 1450 MHz with a small signal gain of up to 64 dB and has a noise figure of 1.3 dB.

The TR61 can be interfaced directly with the antenna feed, thereby providing maximum efficiency during operation. It is designed to meet MIL-STD-810G environmental requirements and has undergone salt fog, sand, dust, shock, rain, and altitude testing to ensure high stability. This system requires a DC supply of 22-56 V and consumes less than 120 W of power. It is available in a module that measures 6.85 x 6.71 x 4.29 inches with N-type (female) connectors for Tx/Rx interface and PT07E14-12P interface for power, monitoring, and control. This TR61 is ideal for satellite communications applications.
