DTRDM Multi-mode S Band Transmitter

This new digital telemetry transmitter supports PCM/FM, SOQPSK-TG and multi-h CPM modulations and provides 10W output power in S band.

Many parameters (Modulation type, Carrier frequency, RF output power data rate and others) are configurable by software to meet most system requirements and to offer a complete solution to your data link needs.

Small size, light weight and robustness make it ideal for integration in very limited space.
