SSTRX-1100 Satellite Transceiver

The SSTRX-1100 dual redundant S-Band Satellite Transceiver is build using SSTRX-1000 unit modules to form a very compact and robust design. It has been designed to operate very reliably within the severe environments of satellites and other space vehicles and has been qualified for the use within LEO-satellites.

The SSTRX-1100 system operates in the S-Band frequency band. It is optimized for bi-directional transmission of commands and telemetry data between the ground station and the satellite.

The SSTRX-1100 dual redundant transceiver system consists two BPSK Telemetry Transmitters, two Telecommand Receivers with integrated a Bit Synchronizer/Data Regenerator, two Diplexing Filters and a 3dB-Hybrid.
