Wireless Intercom System PCB Assembly



First of all, in order not to affect the high-frequency characteristics, we use a multi-layer board in the production of the board map. We use a linear step-down chip in the power circuit of the wireless walkie-talkie. The chip has the function of an internal integrated overheating protection and current limiting circuit, so that the input voltage is stabilized at 5V. Then the voice power amplifier uses NS8002 power amplifier chip, 1W stereo audio amplifier. Its amplified frequency range is 20HZ≤f≤20KHz, and can amplify the power of audio signals emitted by people. At the same time, the regulator also has a small ceramic capacitor load. The regulator has the function of adjusting error detection, and can also limit the band gap voltage reference and constant current. The radio frequency module outputs the voice pin, and its voice signal is weak. It is amplified by the linear step-down chip to drive the external 8 ohm 1W speaker, and the sound effect is good. When in the receiving state, in order to prevent background noise from interfering with the audio circuit, the pins are set. The bypass capacitor is used to filter out the clutter well. The above is the composition of the entire sound collection circuit. Such a sound collection circuit can be used by inputting the output signal to the pins of the radio frequency module. After assembly, select an FM receiver and tune to a certain frequency that does not have a broadcasting station. Repeat the same steps for the unused frequency to test. When the sound can be clearly received on the receiver, the test is completed.
