S-band PC/104 Radio
Full-duplex S-band radio
for aerospace and space.
A tunable radio card for aerospace and space applications, on a CubeSat PC/104 card that works from 1U up. A space-rated variant is available. Separate transmit and receive chains cover 2.0–2.5 GHz, and the host connects over CAN, I²C or UART, with USB-C for ground test.
