1. Interferometer of a microwave frequency discriminator containing power dividers and directional couplers, characterized in that on a plate (1) comprising part of an interferometer based on an asymmetric strip line technique are two 3dB power dividers (3 and 6) and three 3dB/90 degrees directional couplers (9, 10 and 17), where the input port of 3dB power divider (3) is connected via a transmission line to the input port of the interferometer (2), and one of its output ports is connected via a transmission line (4), microwave connector (21), external transmission line (20) and second microwave connector (18) to the input port of the internal 3dB/90 degrees directional coupler (17), whose direct and coupled ports are connected via transmission lines (15 and 16) to the ports of two external 3dB/90 degrees directional couplers (9 and 10), and the insulated port of that coupler is connected via a transmission line (19) to a resistance equal to the wave impedance, while the second output port of 3dB power divider (3) is connected via a transmission line (5) to the input port of 3dB power divider (6), whose output port is connected via transmission lines (7 and 8) to the insulated ports of the external 3dB/90 degrees directional couplers (9 and 19), the remaining four ports being connected via transmission lines to the microwave connectors (11, 12, 13 and 14) which are the output ports of the interferometer.<IMAGE>
