WIDEBAND DIFFERENTIAL ATTENUATOR Russian patent published in 2014 - IPC H03H7/24 

FIELD: instrumentation.

SUBSTANCE: wideband differential attenuator comprises 1^st and 2^nd inputs with 1^st resistor connected there between. 2^nd resistor is connected in AC circuit between device 1^st output and common bus. 1^st load capacitor is connected in parallel with 2^nd resistor. 3^rd resistor is connected in circuit between 1^st correcting capacitor, 2^nd counter phase input and 2^nd counter phase output. 4^th resistor is connected in AC circuit between 2^nd counter phase output and common bus. 2^nd load capacitor is connected in parallel with 4^th resistor and 2^nd correcting capacitor. Device 1^st output is connected with the device counter phase output via 1^st correcting capacitor and 1^st extra inverting current amplifier, all connected in series. 2^nd counter phase output is connected with the device 1^st output via 2^nd correcting capacitor connected in series with 2^nd extra inverting current amplifier.

EFFECT: wider operating frequency band, accelerated response.
