FIELD: radio engineering.
SUBSTANCE: device for matching the radio transmitting antenna-feeder path with antennas of various types, containing a control device, two pre-setting nodes, two similar distributed-type matching circuits, two high-frequency relays P1 and P2 at the input and output of the device and operating in different subbands of the operating frequency range, additionally introduced is a TWR and antenna input impedance sensor that provides information about the TWR and the input impedance of the antenna to the control device via the information-logical interfacing bus.
EFFECT: possibility of matching the radio transmitting antenna-feeder path with antennas of various types, reducing the tuning time to a given frequency and increasing the traveling wave ratio (TWR) in the antenna-feeder path over the entire operating frequency range.
