CONTROL SCHEME Russian patent published in 2009 - IPC H03F1/32 H03F3/189 H03F3/20 

FIELD: radio engineering.

SUBSTANCE: control scheme contains many terminals for signal input and output and coordinating component meant for coordination of signal input and signal output at terminals, at least one block of controlled active resistance engaged between coordinating component and ground and meant for alteration of active resistance at at least one terminal of amplitude control scheme. Control scheme for signal amplitude control may also contain many terminals for signal input and output and at least one couple of blocks of controlled impedance. Each couple of blocks of controlled impedance is engaged between couple of terminals for signal input and output. Each of blocks of controlled impedance is engaged in parallel between signal line and ground. Blocks of controlled impedance in each couple have reactive impedances complementary to each other.

EFFECT: increase of operation speed, assurance of high speed of control and enlargement of control range with possibility of use at high frequencies.
