FREQUENCY CONVERTER Russian patent published in 2025 - IPC H04B1/40 H04B7/15 

FIELD: radio communication equipment.

SUBSTANCE: invention relates to radio communication equipment and can be used as part of radio communication and data transmission systems as high-linear reception and transmission channels, which enable to transmit and receive signals with high modulation types for organizing radio relay communication lines. Frequency converter comprises receiving path (1) and transmitting path (2), placed in a single housing on one board, and frequency synthesizer (3). Receiving path (1) contains series-connected gate (4), low-noise amplifier (5), controlled attenuator (6), balanced mixer (7), coupler (8), band-pass filter (9) for intermediate frequency (IF) of receiving path (1), controlled IF attenuator (10), IF signal amplifier (11), IF band-pass filter (12), IF signal amplifier (13), IF controlled attenuator (14) and IF signal amplifier (15). Transmitting path (2) comprises series-connected band-pass filter (16), IF signal amplifier (17), coupler (18), balanced mixer (19), controlled attenuator (20), high-frequency signal amplifier (21) and power amplification module (22), as well as signal control and processing unit (29). Power amplification module (22) includes coupler (23), high-frequency signal amplifiers (24 and 25) and series-connected coupler (26), gate (27) and feedthrough detector (28). Signal control and processing unit (29) includes analogue-to-digital converter (ADC) (30), digital temperature sensor (31) and protection key (32). Frequency synthesizer (3) comprises series-connected reference frequency generator (33), synthesizer microcircuit (34), frequency synthesizer (FS) signal amplifier (35) and FS signal power divider (36). Frequency synthesizer (3) is a heterodyne for receiving path (1) of the article and a frequency exciter for transmitting path (2).

EFFECT: broader functional capabilities of the frequency converter, wider range of operating frequencies, increased volume of transmitted information, reduced power consumption and reduced overall dimensions.
