CONTROLLABLE MICROSTRIP CORRECTOR OF GAIN-FREQUENCY CHARACTERISTIC SLOPE Russian patent published in 2004 - IPC

FIELD: radio engineering; equalizing gain-frequency characteristic of microwave channels.

SUBSTANCE: proposed corrector of gain-frequency characteristic slope provided with correction level regulating components has input and output lines; quarter-wave section of coupled lines with first and second short-circuited resonators made in the form of microstrip stubs and inserted in its diagonal branches; and also first and second p-i-n diodes and first and second chokes; first p-i-n diode is inserted between first diagonal branch of quarter-wave length of coupled lines and first resonator; second p-i-n diode is connected between second diagonal branch of quarter-wave section of coupled lines and second resonator; first lead of first choke is connected to anode of first p-i-n diode and second one functions as input of first control voltage; first lead of second choke is connected to anode of second p-i-n diode and second one functions as input of second control voltage.

EFFECT: enlarged operating frequency band, reduced quadrature component of gain-frequency characteristic.
