WIDEBAND DIFFERENTIAL ATTENUATOR

摘要

FIELD: instrumentation.SUBSTANCE: wideband differential attenuator comprises 1and 2inputs with 1resistor connected there between. 2resistor is connected in AC circuit between device 1output and common bus. 1load capacitor is connected in parallel with 2resistor. 3resistor is connected in circuit between 1correcting capacitor, 2counter phase input and 2counter phase output. 4resistor is connected in AC circuit between 2counter phase output and common bus. 2load capacitor is connected in parallel with 4resistor and 2correcting capacitor. Device 1output is connected with the device counter phase output via 1correcting capacitor and 1extra inverting current amplifier, all connected in series. 2counter phase output is connected with the device 1output via 2correcting capacitor connected in series with 2extra inverting current amplifier.EFFECT: wider operating frequency band, accelerated response.2 cl, 4 dwg
