Low Power Universal Direct Conversion Transmit and Receive (UTR) RF Module for Software Defined Radios, Phase II

Completed Technology Project

Project Introduction

Low Power Universal Direct Conversion Transmit and Receive (UTR) RF Module for Software Defined Radios, Phase II
Conventional software defined radio (SDR) backend signal processors are limited by a priori system definition and RF hardware. Ideally, advanced SDR RF front-end sections would be as flexible as their software back-ends, allowing in-use or in-orbit reconfiguration of original bands and modulation types. The FPMA/UTR proposed herein should meet this challenge. This proposed Innovation is a distillation of Phase I concept evaluations with the goal of yielding a producible and functional prototype with Phase II funding. The proposed RF front-end provides a post-launch, in-orbit reconfigurable RF module and is capable of Hz to >150GHz bandwidth. Benefits include vastly reduced shelf inventory of equipment addressing different RF requirements and permits ever-ready deployment capabilities using a single piece of equipment featuring this proposed RF front-end. The UTR/FPMA's modular open architecture fully complements the flexibility of SDR technology. The UTR/FPMA services communications or radar functionality, narrow (kbps) to ultra-wideband (GHz) modulation bandwidths, center frequencies scalable >150 GHz: herein UHF to Ka band. Small size and exceptional robustness (radiation hardness, reliability) are expected due to low active component count and mainstream manufacturing techniques. The UTR/FPMA RF module uses only conventional technologies but can yield excellent SW&P characteristics. More »
