APPARATUS FOR INSPECTING MICROWAVE CONNECTORS OF PARTITIONED PHASED ANTENNA ARRAY Russian patent published in 2015 - IPC G01R27/06 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio-measurement equipment and can be used to inspect microwave connectors in multichannel devices. The apparatus includes a continuous microwave oscillation generator and a microwave communication device. The primary input and output of the microwave communication device are connected to the output of the microwave generator and one of the inputs of the inspected partition of the phased antenna array. Each output of the phased antenna array partition has a controlled phase changer. The apparatus also includes series-connected microwave detector and selective amplifier for signals of frequency Fm, as well as a generator for keying signals of frequency Fm and a display. The input of the microwave detector is connected to the secondary output of the microwave communication device. The apparatus also includes a synchronous detector and a control signal switch. The signal input and output of the synchronous detector are connected to the output of the selective amplifier for signals of frequency Fm and the input of the display. The outputs of the control signal switch are connected through control inputs of the inspected phased antenna array partition with 90° inputs of the controlled phase changers. The outputs of the generator for keying signals of frequency Fm are connected to the reference input of the synchronous detector and the input of the control signal switch. The microwave detector used is an amplitude microwave detector.

EFFECT: enabling inspection of each microwave connector and high accuracy of inspection.
