ANTENNA MATCHING DEVICE UMW RANGE FOR SIGNALS WITH PSEUDO-RANDOM TUNING OF THE OPERATING FREQUENCY Russian patent published in 2022 - IPC H03J7/02 

FIELD: matching antenna devices.

SUBSTANCE: invention relates to matching antenna devices and can be used in circuits that allow automatic conversion of the input impedance of the antenna to ensure optimal operation of the transmitter power amplifier in the UMW range with pseudo-random hopping of the operating frequency (PROP). To achieve the effect, the device contains a central processor, a transceiver, flash memory, relay drivers, switchable relays, an analogue-to-digital ADC converter, a bidirectional coupler made in its secondary lines with two detectors for measuring incident and reflected waves. The device also contains a PD phase detector and a power meter. Wherein the central processor is designed to provide the calculation of the SWR, its dispersion, the average SWR value, the noise level in the radio frequency transmission channel from the transceiver to the transmit-receive antenna and the calculation of the impedance of the transmit-receive antenna. The device also contains a block for correcting the time constant of the input resistance of the block LC links.

EFFECT: reducing the time of the transient process during the formation of short pulses, which reduces the energy of the pulses.
