Abstract : A microwave rat-race mixer including a ring shaped transmission line and five transmission lines connected to the ring. Two of the transmission lines are connected to beam lead diodes and symmetrically positioned with respect to a third transmission line which carries the RF signal. A fourth transmission line carries the local oscillator (LO) signal. The fifth transmission line, symmetrically located with respect to the aforesaid first two transmission lines, is connected to the ring. Filters in the RF transmission line and the local oscillator transmission line pass RF and LO signals, respectively, and block intermediate frequency (IF) signals. A filter in the fifth transmission line passes the intermediate frequency signals and blocks the RF and LO frequency signals whereby the intermediate frequency signals are extracted from the ring via the fifth transmission line.
