S-Band Transmitters for Space Launch Applications

DTRDM:

DTRDM S-Band Transmitter

Initially designed with the Ariane project in mind, the DTRDM 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. It is also ITAR free and CE marked.

 

Key Functional Specifications:

  • 1 RF output.
  • S band frequency, 2180 - 2485MHz, in 500kHz tuning steps.
  • Output power from 10 W (+40 dBm) to 10mW (+10dBm).
  • Programmable modulations (IRIG 106): Tier 0 (PCM/FM), Tier I (SOQPSK-TG) and Tier II (Multi-h CPM)
  • Bit rate up to 36Mbps (Tier I and Tier II) and 18Mbps (Tier 0).
  • Embedded Viterbi encoder (1/2, 7).
  • Embedded IRIG LDPC encoder (R=1/2, 2/3, 4/5 & k=1024, 4096).

  • Input: Data/Clock (RS422).
  • Remote RF output power control.
  • Small size 3.2" x 4" x 1.3"(82 x 102 x 33mm).

 

CMA TRS:

CMA TRS S-Band Transmitter

The TRS module is an application module for the Safran Data Systems CMA Series.

This module is a fully digital transmitter. It supports PCM/FM and SOQPSK-TG modulation and provides 5W output power in S band. Many parameters (Modulation type, carrier frequency, RF output power, data rate and others) are configurable by software (RS232 format) to meet most system requirements and to offer a complete solution to your data link needs.

Like other application modules, the TRS module is meant to be inserted in a CMA Data acquisition Unit (DAU), and must be placed between the CPU and the stack cover of a Core-8 DAU stack.

 

Key Functional Specifications:

  • S band frequency, 2180 - 2480MHz, in 500kHz tuning steps.
  • Output power from 5mW to 5W minimum.
  • Programmable modulations (IRIG 106): Tier 0 (PCM/FM), Tier I (SOQPSK-TG)
  • Bit rate up to 40Mbps.
  • Input: Data/Clock (RS422).
  • Remote RF output power control.
