Space Micro Inc. — Department of Defense SBIR Phase I: Space Micro will develop an electrically reprogrammable, Radiation Hardened Sampled IF Fil

Description

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.
