OPTICALLY CONTROLLED MILLIMETER RANGE SWITCH AND DEVICES BASED ON IT Russian patent published in 2019 - IPC H01P1/15 

FIELD: radio equipment; electronics.

SUBSTANCE: invention relates to radio engineering, more specifically to an optically controlled millimeter-wave switch based on photoconductive elements implemented in a printed circuit board. According to the invention, the optically controlled switch comprises a printed circuit board, moreover, the signal layer of the printed circuit board contains a microstrip conductor and a matching element; shunt metallized hole located in the dielectric layer between the signal and earth layers of the printed circuit board and separated from the ground layer of the printed circuit board by the dielectric gap, moreover, the shunt hole has an electrical connection with a microstrip conductor and with a matching element; photoconductive semiconductor element located on the earth layer of the printed circuit board and electrically connected to the shunt hole and to the signal layer of the printed circuit board, moreover, the photoconductive element has a dielectric state in the absence of a control luminous flux and a conductor state in the presence of a control luminous flux, moreover, the matching element is designed to compensate for the parasitic capacitance arising in the gap between the contact pad of the shunt hole and the ground, and has inductive properties in the operating frequency range of the switch. Also disclosed are devices based on an optically controlled switch.

EFFECT: simplifying the design, providing an improved isolation circuit of the power/control from the RF path, reducing losses at high frequencies, increasing the allowable power output and simplified integration into the printed circuit board.
