CubeSat UHF Digital Radio Transceiver SatCOM UHF

CubeSat UHF Digital Radio Transceiver SatCOM UHF

The UHF radio utilizes a half-duplex architecture with high-performance low power consumption transceiver which is controlled by a dedicated ARM Cortex-M4 MCU. The radio uses ultra-high frequency band (UHF) that is programmable in 395 to 440 MHz range.

The module supports GFSK2 or GFSK4 modulation and 2400 to 38400 bit rates. Modulation is configured to be ¼ of symbol rate and consequently, it is MSK modulation.
