PWYJT27TX86100RADIO CONTROL CAR

Jada Toys Co. Ltd. Model No: 83011/83014/83022 Transmitter and receiver Circuitry Operating Description: Transmitter Unit: When the power switch turn to “ON”,Q4 and the crystal produce a carrier frequency , press one of the keys K1 (Forward or Backward) , K2(Left or Right), The Encode IC TX-2 give the signal out and Q5 to modulation after amplifier the signal and transmit from antenna. Receiver Unit: The modulation signal receive from the antenna and pass to local oscillation and demodulation from Q1, the encoding signal transfer to Decode IC RX-2 after decoding the direct control signal go to the motor driver unit,the Q3～Q8 control Forward and Backward, the Q9～Q12 control Left and Right.

It operates at 27.145MHz and the oscillation of radio control is generated by a crystal. The EUT is powered by 1x 9V size battery. There are two control sticks on the EUT. When the forward, backward, turn right or turn left stick is pushed, it will transmit different radio control signal to the receiver. The brief circuit description is listed as follows: - Q5 and associated circuit act as a RF amplifier. - Y1, Q4 and associated circuit act as an oscillator. - Z1 and associated circuit act as a voltage regula…
