DEVICE FOR DISTRIBUTION AND PHASING OF SUPER-HIGH FREQUENCY SIGNAL Russian patent published in 2019 - IPC H01P1/18 H01Q3/34 

FIELD: physics.

SUBSTANCE: invention relates to microwave (UHF) equipment and is intended for division or summation of microwave power during operation in phase antenna arrays (PAA) or active phase antenna arrays (APAA) respectively in modes of transmission and reception with electronically controlled phase of passing microwave signal in each of channels. Device for distribution and phasing of microwave signal comprises power divider on microstrip lines, input/output of which is input/output of device, each input/output of power divider is connected to input/output of pin-diode microstrip discharge phase changers, made of series-connected discharges of 22.5°; 45°; 90°; 180°, which inputs/outputs are connected to coaxial-microstrip transitions, which are inputs/outputs of the device. Control outputs of control device are connected to power supply filters connected to control inputs of corresponding bits of phase changers. Power divider is made with (N-4) channel, where N>5 is integer. Each pin-diode microstrip phase shifter additionally includes bits 5.625° and 11.25°, made on loaded line and combined on one matching section of microstrip line, made in form of meander with electromagnet coupling. Ranks 22.5° and 45° are made on the basis of loop phase changers with coupling in loop and additional pin-diode in rupture of short-circuiting matching loop connected to top of loop of each discharge. Besides, pin-diode discharge 90° is made on the basis of compactly folded interdigital directional coupler with diodes connected to housing on ends of high-resistance loops, connected to internal arms of interdigital coupler. All circuits of connection with housing are connected to main path through interference suppression filters, besides, control inputs of additional bits 5.625° and 11.25° are connected to power supply filters connected to corresponding additional outputs of control device.

EFFECT: increasing the number of phase discharges in the phase changers of the distribution device and phasing the super-high frequency signal with the least bit of 5.625° and reduction of phase errors without increase in weight and dimensions.
