The present invention utilizes a thermally controlled TR module test fixture TCMF that is a self-contained microwave test fixture for convenient, accurate testing and characterizing transmitreceive TR modules which are being thermally cycled. The thermally controlled TR module test fixture comprises a multi-stage thermoelectric cooling module which provides an 80 degree centigrade temperature differential and is mounted to an adjustable test support that is capable of holding in place a monolithic microwave integrated circuit MMIC transmitreceive module. The thermally controlled TR module text fixture can be used in numerous automated measurement test systems for acquiring MMIC TR module data as a function of thermal cycling such a s-parameters and noise figure. A thermally controlled TR module test apparatus utilizing a multi-stage thermoelectric cooling module to maintain a TR module at predetermined temperature during test measurements. The thermoelectric cooling module provides a cooling capacity of 9 watts and a temperature differential of 80 centigrade which allows the TR module to be thermally cycled during the test measurements.
