ONBOARD REPEATER TRANSCEIVER Russian patent published in 2020 - IPC H04B7/185 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering and can be used for transmitting and receiving signals in satellite communication systems. Transceiver includes a receiver, a transmitter and an information processing unit (IPU). Receiver comprises series-connected disconnector of receiving antenna, first band-pass filter (BPF), directional coupler (DC), protective device, low-noise amplifier, second BPF, high frequency amplifier (HFA), a quadrature mixer with a connected frequency synthesizer (FS), connected to the first output of the quadrature mixer are connected in series the first low-pass filter (LPF), video amplifier (VA), analogue-to-digital converter (ADC), to second – series-connected second LPF, VA and ADC, besides, outputs of ADC are connected to inputs of IPU. Transmitter comprises in-series connected FS, connected to IPU, quadrature phase manipulator, control inputs of which are connected to outputs of IPU, HFA, power amplifier, DC and switch of transmitting antenna. Into the transceiver there introduced is a system of inbuilt monitoring, which includes serially connected FS, a mixer connected to the DC transmitter, the third BPF, the inbuilt monitoring system switch connected to the DC receiver.

EFFECT: providing adjustment and autonomous monitoring of serviceability of the transceiving system.
