RLC HIGH-FREQUENCY FILTER ON VOLTAGE REPEATERS Russian patent published in 2022 - IPC H03H11/12 

FIELD: radio engineering.

SUBSTANCE: RLC filter is proposed, containing input (1) and output (2) of the device, frequency-setting inductance (3) and frequency-setting capacitor (4), as well as matching resistor (5). The circuit includes first (6), second (7), and third (8) additional voltage repeaters. Device input (1) is connected to device output (2) through sequentially connected matching resistor (5) and first (9) additional resistor, a common node of which is connected to an input of second (7) additional voltage repeater, an output of which is connected to an input of first (6) additional voltage repeater through frequency-setting capacitor (4). Device output (2) is connected to a common bus of a power supply source through sequentially connected second (10) and third (11) additional resistors, a common node of which is connected to an input of third (8) additional voltage repeater.

EFFECT: possibility of independent setting with different resistors of a pole frequency and a pole Q-factor with constant values of capacity of a frequency-setting capacitor and frequency-setting inductance.
