Tiger Innovations has a great deal of experience designing and fabricating RF devices and support equipment for both space based and terrestrial applications. We specialize in designing highly capable, low mass, low power RF transceivers and software defined radios. The RFX-400 provides a cost effective, extremely small form-factor UHF transceiver for spacecraft communication. It supports multiple modulation formats, encryption algorithms, and data protocols. It features very low power standby mode, digitally tunable frequency, and variable power output up to 8.1W. Applications include ground terminals, cubesat RF modules, and ground gateway stations.
