Abstract :
A full 6-18-GHz transmit/receive (T/R) module is demonstrated for multifunction phased-array applications utilizing a family of high-performance MMICs (monolithic microwave integrated circuits). Featured are output powers reaching over 1.0 W, a 4:1 bandwidth 5-b digital phase shifter, a low-loss, high-isolation switch, and a high-dynamic-range design incorporating all required system functions. It is shown that the performance of the 4:1 bandwidth digital phase shifter and the DC-20 GHz low-loss high-isolation switch surpasses all previously presented results.<>
