Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Fig. 1, a kind of intercom high speed is to frequency data transmission system, including MCU circuit module 1, MCU circuit mould The output end of block 1 is electrically connected with APC control module 2；Since APC control module 2 and RF radio-frequency module 10 are controlled by MCU simultaneously Circuit module 1, to realize radiofrequency signal amplification output；

The output end of APC control module 2 is electrically connected with radio-frequency switch module 3, since radio-frequency switch module 3 is controlled simultaneously In APC control module 2 and RF radio-frequency module 10, to realize the normal amplification output and stopping movement of radiofrequency signal；Radio frequency The output end of switch module 3 is electrically connected with bandpass filter module 4, and the output end of bandpass filter module 4 is electrically connected with antenna Pole module 5 is amplified the signal exported when 4 pairs of bandpass filter module and is filtered, and allows the wave of special frequency channel to pass through same When shield other frequency ranges, and effectively transmitted by antenna pole module 5；The output end of antenna pole module 5 is electrically connected with LNA mould Block 6 effectively puts small-signal by LNA module 6 after antenna pole module 5 captures aerial big signal electromagnetic wave Greatly；The output end of LNA module 6 is electrically connected with detecting circuit module 7, by detecting circuit module 7 to filtered modulating wave into The corresponding demodulation of row, useful RXD signal is separated from high-frequency signal；The output end of detecting circuit module 7 is electrically connected with RC filter module 8, the output end of RC filter module 8 are electrically connected with shaping circuit module 9, the output end electricity of shaping circuit module 9 The input terminal for connecting MCU circuit module 1 obtains final required square wave letter by RC filter module 8 and shaping circuit module 9 It after number, exports to MCU circuit module 1, keeps TXD transmitter synchronous with RXD receiver frequency information data, to frequency success；RF is penetrated The input terminal of the output end electrical connection radio-frequency switch module 3 of frequency module 10；Since RF radio-frequency module 10 is super outer using traditional circuit Poor scheme and Highgrade integration radio frequency chip scheme, therefore after the processing of RF radio-frequency module 10, simultaneously with APC control module 2 Radio-frequency switch module 3 is acted on, radio-frequency carrier and power amplifier offset voltage are provided it, faint electric signal is carried out effective Amplification output.
