Description

General Dynamics’ space-qualified HRT-440 Mission Data Transmitter will maximize your data downlink at X-Band. Implementing the powerful new CCSDS Low Density Parity Check (LDPC) code, the performance of this state-of-the-art unit approaches the Shannon theoretical limit for channel capacity. Standard operation is SQPSK modulation at the traditional 8.2 GHz downlink band, with options available for Tracking and Data Relay Satellite System (TDRSS) Ku-Band or Ka-Band operation.

The HRT-440 utilizes the latest space-qualified and radiation hardened FPGA, ASIC, and GaAs MMIC technology. Implemented using space-proven design techniques from our line of transponders, the result is a high-performance and reliable unit with a very small size, low mass and power.

The transmitter includes a low power, level-controlled output suitable for driving power amplifiers. An optional 15-Watt solid state power amplifier (SSPA) can be provided if desired for feeding downlink antennas.
