X-Band High Data Rate Trellis Coded 8PSK Transmitter for Earth Observation Satellite Data Transmission

This paper presents a trellis coded 8PSK transmitter equipment designed for space applications. It enables high data rate transmission for Earth observation satellites. The equipment is based on channel coding functions implemented in FPGA circuits, a MMIC medium level RF chain, including a MMIC direct 8PSK modulator, an Hybrid 6 W output amplifier and features a direct X band Local Oscillator (LO). Data rates up to 4 × 155.5 Mbps can be achieved. Design description and Engineering Model performances are provided in this paper.
