Reconfigurable Digital Transceiver (RDT) for Space Applications

ABSTRACT: IAI proposes the design of a Reconfigurable Digital Transceiver (RDT), to achieve the goals of this solicitation. The proposed design will be prototyped in the earlier phases on a custom Multi-Channel Digital Synthesizer and Processor (MCDSP) platform that has been designed and field-tested by IAI for digital transceiver applications. Our innovation for this Phase-I is focused on integrating fixed crystal oscillator based transceivers with wideband digital frequency synthesis capability to cover Space-to-Ground Link Subsystem (SGLS) and the Unified-S band. We list Our approach proposes the use of a single 2.4 GHz oscillator and augmenting wideband direct digital synthesizers to cover the entire SGLS/ Unified S-band spectrum. The entire RDT design is proposed with space grade components, including conservative design strategies which increase the probability of future space qualification. BENEFIT: Military applications of this technology include spacecraft transceivers, UAS transceivers, and tactical radios for ground soldiers and weapon systems. The most promising commercial applications of the proposed programmable frequency transceiver besides spacecraft transceivers are: Extra Vehicular Activity (EVA) radio for astronauts and rovers Arbitrary wideband waveform synthesizers and processors Reconfigurable Cognitive radio with multi-mode capabilities Multi-protocol programmable radios
