FIELD: radio engineering, communication.
SUBSTANCE: device comprises: separating capacitors in series LC oscillatory decoupling circuits (C1, C4, C7); circuit capacitors in parallel LC oscillatory filter circuits (C2, C5, C8); circuit capacitors in parallel LC oscillatory decoupling circuits (C3, C6); blocking capacitors (C9, C10); inductors in series LC oscillatory decoupling circuits (L1, L4, L7); inductors in parallel LC oscillatory filter circuits (L2, L5, L8); inductors in parallel LC oscillatory decoupling circuits (L3, L6); limiting resistors (R1, R2, R3); PIN diodes (VD1, VD2, VD3, VD4); signal terminals of the device (11, 12, 13); control voltage sources (26, 27).
EFFECT: improved frequency selectivity, size and weight parameters of the system due to combining switching and filter elements in one device.
