Radio remote control transmitter and receiver head circuit diagram
The circuits of transmitting part and receiving part are shown as above. Radio remote control transmitter T630 is a micro-transmitter without the signal. Its emission frequency is 265MHz, and the power supply is 12V. Remote control distance is 100M, operating current is only 4mA, the volume is 28X12X10mm. Radio receiver T631has a built-in antenna. It is the samewith the TV tuner receiver, demodulator. Its typical operating voltage is 6V. Its waiting current is 1mA. Receiver frequency is 265MHz, its volume is only 31X23X10mm. They can be easily used to produce a variety of radio-controlled device with the features of miniaturization, transmission distance, power consumption, anti-interference ability and so on. They can easily replace the infrared, ultrasonic transmitter and receiver. Radio head T630 circuit is shown as below. Four launch tubes V1 circuit and external components C1, C2, L1, L2 constitute a frequency of 265MHz ultra-high frequency transmitter circuit L2.
