Advanced Reconfigurable Communications Components Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-189 Topic Title: Advanced Reconfigurable Communications Components Proposal No.: N102-189-0122 Firm: Space Micro Inc. 10237 Flanders Court San Diego, California 92121-1526 Contact: Joshua Patin Phone: (858) 332-0700 Web Site: http://www.spacemicro.com/ Abstract: Space Micro will develop an electrically reprogrammable, Radiation Hardened Sampled IF Filter (RH-SIF) for use in space-based reconfigurable RF/microwave SATCOM subsystems. This technology aims to exceed the capability of traditional tunable filter technology. A programmable radio system must have the ability to program the hardware bandwidth. The RH-SIF exceeds the capabilities of active analog filters in terms of linear phase without sacrificing rejection, simple tuning scheme by varying the sample rate, and potential for high dynamic range with lower power consumption. The RH-SIF takes advantage of signal processing concepts used in finite impulse response (FIR) filter design. A radiation hardened sampled IF filter will be designed and manufactured in commercially available CMOS or SiGe ASIC processes. Benefits: Many future satellite communications (SATCOM) missions could utilize RH-SIF technology to increase agility while reducing the size, weight, and power consumption (SWaP) of the system. Furthermore, RH-SIF technology would improve a satellite communication system's reliability through radiation hardness and reduction of parts count. Futhermore, the reduced parts count lends itself to a more affordable solution. For future software defined radios (SDR) including the newly developed Joint Tactical Radio System (JTRS) support network, SWaP and reliability are key issues. Critical SATCOM missions include future Mobile User Objective System (MUOS) satellites, as well as potential MUOS supporting small and nano-satellites, such as CubeSats. In these nano-satellites, the SWaP and affordability offered by RH-SIF are especially important. Return
