The Transmit-Receive Multi Modules (TRMM) 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 the 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 the 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 Module for Phased Array RADAR 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 Multi Modules can replace Radars with a mechanically steered antenna. The Transmit-Receive Modules are ideal for various applications, namely, Surveillance Radars, Weather Radars and Satellite Communications.
