CONTROLLED POWER SPLITTER Russian patent published in 2005 - IPC

FIELD: high-frequency and microwave engineering.

SUBSTANCE: proposed controlled power splitter that can be used in systems where controlled distribution of microwave power between two loads is essential has tee-junction, control circuits, and decoupling capacitors. Each side of tee-junction is, essentially, variable filter whose resistors are formed by series connection of two sections of transmission line through varactor, and control voltage is supplied through resistors. Power splitting is effected by tuning away frequency of one of filters for which purpose control voltage is applied to its varactors.

EFFECT: stepless gain control, reduced control power, enhanced speed of control.
