DIFFERENTIAL ATTENUATOR WITH EXPANDED OPERATING FREQUENCY RANGE Russian patent published in 2014 - IPC H01P1/22 

FIELD: radio engineering, communication.

SUBSTANCE: device contains the first input (1), the first output (2), the first resistor (3), the second resistor (4), common bus (5), the first (6) load capacitor, the second resistor (4), the first balancing capacitor (7), the second antiphase input (8), the second antiphase output (9), the third resistor (10), the fourth (11), the second load capacitor (12), the second balancing capacitor (13). The first output (2) of the device is connected to the input (14) of the first (15) complementary non-inverting current amplifier via the first balancing capacitor (7). Current output of the first (15) complementary non-inverting current amplifier is connected to the first output (2) of the device. The second antiphase output (9) of the device is connected to the input (16) of the second (17) complementary non-inverting current amplifier via the second (13) balancing capacitor. Current output of the second (17) complementary non-inverting current amplifier (13) is connected to the second antiphase output (9) of the device.

EFFECT: better device performance when working with pulse antiphases signals of high amplitude.
