An AD9361 or RadioVerse-class transceiver covers approximately 600 MHz to 6 GHz. This module places a switchable downconverter ahead of the existing radio so the mission can receive above that range without selecting a different radio and rebuilding everything that depends on it. Two modes are selected by a control pin. Bypass passes 600 to 6000 MHz through at 39 to 42 dB gain and 2 to 3.5 dB noise figure. Extender mode switches in the downconverter for 7 to 12 GHz input at 39 to 44 dB conversion gain and 2.5 to 5 dB noise figure. Antenna and local oscillator selection are separately controllable, so one card can serve two apertures and two conversion plans. Spurious is held to -50 dBm and out-of-band harmonics to 60 dBc, with a 10 MHz external reference input and 1-wire serial temperature reporting. Supply is 12 VDC at 0.33 A in extender mode and 0.19 A in bypass. The card is 96 x 90 x 14 mm (3.77 x 3.55 x 0.55 in) at 201 g with SMP male RF, baseplate conduction cooled, rated -40 to +85 °C. Typical lead time for standard configurations is 8 to 10 weeks.
