11909_FCC 27MHz Tx Block Diagram ANT Battery Encode Amplifier




 U1 Q4 27.145MHz Oscillator Q3 & T1 Voltage Regulator Z1

Operation Description Rally Champion R/C Car (27M) The Rally Champion R/C Car operated at 27.145MHz which is controlled by crystal. It is powered by 1.5V x 8pcs of ìAAî size battery. There are two-control key in the front of the transmitter, when the speed control trigger pressed once, it will transmit a radio frequency for receiver going forward or backward. When the steering wheel turned once, it will transmit a radio frequency for receiver turn left or right. Refer to the transmitter circuit design, the circuit description is listed as below:
 Q3, T1 and associate circuit act as oscillator.
 U1 and associate circuit act as encoder.
Q4 and associate circuit act as amplifier.
 Z1 and associate circuit act as voltage regulator.
