High Reliability Transmitter (HRT-920)

L3Harris' HRT-920 delivers output power up to 17 W with data rate capability to 20 Mbps. The RF output is also fully protected from high VWSR loads as well as short and open conditions.

This unit also provides new breakthroughs in price and performance with simplified internal construction and multi-waveform & encoding capability. Fully synthesized channel selection is offered via factory fixed or external user control. Standard off-the-shelf waveforms are available or may be customized to user needs. Improved capabilities are provided while still meeting or exceeding the most stringent operational requirements.

The transmitter may be provided with the common analog and digital modulation waveforms as well as user defined custom implementations. Digital and analog data interfaces are provided as well as an IRIG 106-11 serial control and status interface.

This transmitter provides MIL-SPEC quality and environmental capability, while maintaining compliance with IRIG 106-11 and tailored MIL-STD-461F EMI requirements.
