Abstract : The present invention utilizes a thermally controlled T/R module test fixture (TCMF) that is a self-contained microwave test fixture for convenient, accurate testing and characterizing transmit/receive (T/R) modules which are being thermally cycled. The thermally controlled T/R 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) transmit/receive module. The thermally controlled T/R module text fixture can be used in numerous automated measurement test systems for acquiring MMIC T/R module data as a function of thermal cycling such a s-parameters and noise figure. A thermally controlled T/R module test apparatus utilizing a multi-stage thermoelectric cooling module to maintain a T/R 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 T/R module to be thermally cycled during the test measurements.
