S-Band Transceiver

S-Band Transceiver image


The ISISPACE CubeSat compatible S-band Transceiver is comprised of two PCBs, designed to meet the needs of telemetry downlinks, high data-rate downlinks of up to 4.3 Mbps (usable information bit-rate at CCSDS transfer frame level) and telecommand uplinks of 9.6 kbps (AX.25). The S-band transmitter is flexible, implementing CCSDS as data link layer protocol and allowing in-flight configuration of data-rate, modulation scheme, frequency, and RF output power. The system is designed for full-duplex TT&C and Payload data downlink, a diplexer is used such that a single antenna can be used for uplink and downlink.
