This paper presents a 2.5D integrated X-band eight-channel T/R module with frequency conversion function.It can be used in active phased array radars which employ analog phase scanning in transmitting and digital beam-forming(DBF)in receiving.The proposed T/R module features small size,high integrated level,large output power,and good consistency between different channels.In this paper,the operating principle,composition,SIP RF packaging design,transmit-receive channel specification budgeting,image rejection mixing design,and thermal design of the T/R module are described in detail.Finally,the electrical performance of the T/R module is tested.The test results show that the T/R module has good performance with a transmitting power of greater than 26W,a transmitting phase-shifting accuracy of less than 3.2°,a receiving noise coefficient of less than 3.1dB,and a receiving gain of greater than 62dB.
