Discrete transmission phase shifter new configuration that makes it possible to implement phase shifts up to 90 degrees with the use of only two diodes is described. Phase shifter consists of two equal lines which wave resistance is half as small as input resistance and first diode is included in gap in the middle of one of lines and open loop is connected to the middle of second line through second diode. Tuning phase shifter for multichannel device phase equalization is also built up on the basis of this configuration. Controlled and tuning phase shifters were used in six-channel PAA beam-manipulating device.
