Device for calibrating and testing transmit/receive moduls in an active electronically phased array antenna

Abstract

Abstract The device is used with an additional switching network (SN) incorporated in each transmission/reception module, allowing the transmission and reception signal terminals (A1,A2) of each module to be used for handling the HF test and calibration signals (BIT) provided by the testing and calibration device as well as for the normal transmission and reception signals. Pref. the switching network has 5 terminals, 2 of which act as the transmission and reception terminals, a third coupled to a directional coupler (RK) for input and output of the test and calibration signals and the remaining 2 terminals coupled to respective switches (S1,S2).
