Multiband RF Receiver Front End for Data Relay Ka-band uplinks and crosslinks

NASA TechPort describes this completed GSFC IRAD project as a low-SWaP, low-noise, programmable Ka-band receiver front end for relay uplinks and crosslinks. The prototype covers 22.5–27.5 GHz with at least 200 MHz processing bandwidth and combines wideband filters, mixers, and space-grade high-speed conversion to support lunar and planetary data-relay infrastructure and distributed science missions.
