Trasmit-Receive Multi Module
Compact T/R Modules designed for Phased Array RADARS operating in S-Band based on GaN (Gallium Nitride) technology. Delivers high efficiency in a compact size with a 100W Peak Transmit Power Capability per channel.
Overview
The Transmit-Receive Multi Modules (TRMM) from Mistral are compact T/R Modules for Phased Array RADARS operating in S-Band. Based on GaN (Gallium Nitride) technology, the TRMM delivers high efficiency in a compact size with a 100W Peak Transmit Power Capability per channel.
The Transmitters designed by Mistral have a unique calibration feature, which biases the Power Amplifier to optimum point at all ambient temperatures in the operating range. It also, has dynamic output power control which is carried out by measuring the RF power output and altering Power Amplifier DC supply resulting in maximum efficiency.
The digital control and GUI interface to the unit is implemented on a Virtex-4 series FPGA housed on a separate controller card. The card also has a Health Monitoring section which monitors the key parameters of the unit. The SRAM and FLASH are used to store and retrieve TRMM calibration and collimation data.
The T/R Modules for Phased Array RADARS is designed to be conduction cooled. It interfaces with a liquid cooled cold plate which is maintained at 20⁰C±10⁰C under all ambient temperature conditions.
The Transmit Receive Module ideally find their application in Surveillance Radars, Weather Radars and Satellite Communications. The TRMM can replace radars with mechanically steered antenna.
