COMPUTER-AIDED DESIGN OF MICROWAVE FOUR-PORT CIRCUITS
微波四端口电路的计算机辅助设计

An analysis method of microwave four-port circuits by using the transfer matrix is presented. The mathematical models of several basic circuit elements and expressions of net-work functions for microwave four-port circuits are given. Furthermore a small general program is also presented which is capable of analysing and optimizing a group of directional couplers, balanced transistor amplifiers and electrically tuned attenuators.
