API's QTRM - Quad Transmit Receive Module (4-Channel T/R Module)

We have developed an approach that supports a LRU (Line Replaceable Unit) for AESA platforms which allows for a ‘common module’ building approach for ease of system integration, first line repair and reduced cost of ownership. We have chosen a QTRM (Quad Transmit Receive Module) as the ‘common module’ that can be integrated into a Plank to form a sub-array. The QTRM is factory calibrated and has the facility for the system integrator to up load ‘Array’ offsets to support aperture tapering etc.,. We also have a range of ‘cooling solutions’ to support different platform applications that can either be implemented at QTRM level or at Plank level. A QTRM includes full RF, dc, control functionality (logic interface), calibration and BITE status for each TRM, thermal, current overload, receive and transmit detectors.
