Abstract

The invention discloses a simple radio frequency receiving detection circuit of a real-time information publishing mobile phone. The circuit comprises a logarithmic amplifier AD8318, a voltage feedback amplifier AD8023, first resistor to eighth resistor, first capacitor to seventh capacitor and a direct current power supply, wherein the logarithmic amplifier AD8318, the first capacitor to the seventh capacitor, the first resistor and the second resistor together form a receiving, detection and primary amplifying circuit; the voltage feedback amplifier AD8023 and the third resistor to the eighth resistor together form a secondary amplifying circuit, and a signal of the former is further amplified by the later, so an output signal distortion is smaller. Real-time receiving, detection and amplification of a radio frequency signal of a surrounding environment are realized by using the logarithmic amplifier AD8318 and the voltage feedback amplifier AD8023; the circuit has high real-time property, simple structure, low cost, small size and convenience in popularization and generalization.

Description

technical field [0001] The invention relates to a detection circuit of a real-time information distribution mobile phone, in particular to a simple radio frequency receiving detection circuit of a real-time information distribution mobile phone. Background technique [0002] With the continuous advancement of electronic technology, mobile phones now have functions such as signal collection, audio and video playback, etc. Mobile phones with implemented signal collection and information release functions are referred to as "real-time information release mobile phones". When the wireless signal device or product is next to it, the wireless signal is automatically collected, and the content of the signal is decoded, and then the audio and video information corresponding to the information is played in real time through the display and speakers to achieve the purpose of information release. [0003] The above-mentioned wireless signals mostly use radio frequency signals, and the ...
