BMW-72021TX49BATTLE WHEELS-KAGU-TSUCHI

Operation Description The transmitter of Battle Wheel Warriors is powered by 1*9.0V battery, it has radio frequency 49.860MHZ. While push the left or the right controller sticks forward or backward, it will transmit a modulation signal for receiver to go left or right , When push both of the left and the right controller, the receiver will go forward or move backward. The antenna of the transmitter is an integral antenna. It is fixed on the PCB. Refer to the transmitter circuit design, the circuit description is listed as below:
 X1, Q2 , and associate components are acted as local oscillator for modulation.
 Q1 and associate components are acted as RF power amplifier.
 U1 and associate components are acted as control signal encoder.

It operates at 49.860MHz and the oscillation of radio control is generated by a crystal. The EUT is powered by a 9V size battery. There are two control sticks on the EUT. When the forward, backward, turn left or turn right stick is pressed, it will transmit different radio control signal to the receiver. The brief circuit description is saved with file name : OpDes.pdf - U1 and associated circuit act as an encoder. - X1, Q2 and associated circuit act as an oscillator. - Q1 and associated circuit act as a RF amplifier.
