Abstract

PURPOSE:To realize a desired impedance conversion in a hybrid circuit by changing properly an impedance ratio of a microstrip line constituting the hybrid circuit and a resistance value of a termination resistor so as to set the impedance. CONSTITUTION:A circuit pattern 9 constituting the hybrid circuit is provided on a dielectric board 1 having an earthing layer 4 on its rear side. The hybrid circuit consists of microstrip lines 91-94. The termination resistor 5 and an input terminal 6 are connected to one end of the lines 91, 94. Moreover, the other end of the lines 92, 94 is formed as output terminals 7, 8. The desired impedance conversion is realized in the hybrid circuit by changing properly the impedance ratio of the lines 91-94 and the termination resistor 5 so as to set the impedance.
