context_page_description: The Iris transponder is a small, low power deep-space transponder designed by JPL for use in cubesats. It unifies a number of communication functions - receiver, command detector, telemetry modulator, exciters, and control functions - into one 1.2-kg package that occupies about 0.5 U. IRIS is designed to handle X band uplink, UHF receive, and both X band and optional Ka band downlink. It is only one third the mass, and lower power, compared to the smallest previous solution, the small deep space transponder.
