PWYJT27TX86000RC Car TX 27 MHz

Block Diagram---27.145MHZ TX 27.145MHZ Oscillator IC(TRS5TB07) Encoding signal output Channel control (A,B,C,D) Key control: (forward,backward,left,right) Modulate & High frequency amplify circuit Antenna

Operational Discription: RC Car Transmitter Schematic Circuit Description: The Transmitter IC is four channels with four functions. The IC encoding signal from pin SO and modulate with 27MHZ oscillator (Q1, XT1 combined 27MHZ oscillator), send to the high frequency amplify circuit (Q2 and other components combined high frequency circuit) then through the band filter and antenna send out. Power on will be light on for LED. RC Car Receiver Schematic Circuit Description: The Receiver is a device which receive carrier signal from Antenna and through the receive circuit to select 27MHZ carrier signal through rectify & amplify circuit (Q1, Q2, Q3, Q4) Then send to IC (TRS5TB07) to decode the carrier signal. The decode signal through the forward & backward and left & right control circuit to drive the motor!

Operating at 27.145MHz which is controlled by a crystal. The EUT is powered by a 9V battery. It has a switch to change from channel A to D. Channel A, B, C and D are using the same carrier frequency (27.145MHz) but with different coding to control the corresponding receiver. When the EUT is turn on, it can transmit forward, backward, turn left or turn right radio signal to the receiver. The brief circuit description is listed as follows : - XT1, Q1 and associated circuit act as oscillator. - TRS5TB07 and associated circuit act as signal encoder. - Q2 and associated circuit act as RF amplifier. - C9, C10, L4 and associated circuit act as low pass filter.
