Abstract

Two lines Ai(i=1 or 2) are connected to an input terminal In. The line Ais grounded via a capacitor C. The line Aand a line Bform a coupled line. One end of the line Bis connected to a positive pole of a diode Dwhich is grounded at its negative pole. Lines Band Bare connected to the other end of the line B. The other end of the line Bis connected to a capacitor Cwhich is grounded at its other end and a resistor Rwhich is connected to a voltage control terminal Vat its other end. The other end of the line Bis connected to the positive pole of a diode D. The line Band the line Aform a coupled line. One end of the line Ais connected to an output terminal Out-i, and the other end is grounded via a capacitor C. The output of the terminals Out-are switched to 5.8 GHz band, 4.8 GHz band and cut-off, by applying to Vand Vthree potentials, that is, ground potential. positive potential which causes no current flow and positive potential which causes current flow.
