摘要： Some embodiments of the present invention provided an impedance-transforming arrangement comprising a plurality of microwave power transistors (41), and at least one intermediate impedance-transforming or matching device (30). The matching device comprises a plurality of elongate microwave transmission lines (31) provided in or on at least one dielectric substrate (32), extending across or through the dielectric substrate. The microwave transmission lines are coupled at one end to the gate pads (47) of the transistor and at the input ends to a signal input terminal for the transmission line. The transmission lines are substantially directly coupled to one another by means of resistive elements (35) providing a current flow path between the two transmission lines in order to reduce any residual tendency to instability caused by manufacturing variations or misalignment in the assembly process.
