Operational Description

Circuit Description Circuit Description When the control key is pressed,A encode signal from U2 is transmitted. Q2 and crystal for osilator,Q1 is rf amp modulation encode signal for rf, signal through filter send by antenna. Antenna and grond circuitry This unit make use an extenal antenna,This antenna is inductively coupled. This unit relies on the ground trace of the printed circuit board.No external ground is provided. energry is supplied by 6pcs aa alkaline battery. Background The device described herein a wirless(RF)TOY car CONTROLLER TRANSMITTER For use with the toy aeroplane controlled receiver.It has only one channel of Operation which the usermay choose only.And is used to send button-status dataform The controller to a wireless receiver connected with motors. Typical opeartion Typical opeartion would innolve the user turning on the unit to the toy game when turned on,The unit comes up on the default channel and transmits a continuously steam data.The user can not,At will .Change to any other of the predefined channel. Configuration The transmitted rf circutiry consists of a crystal controlled oscillator, Follow by rf amplifier & filter and antenna.Tha main characteristics Of this configuration are shown as below: Frequency ranges 27.145MHZ Occupied bandwidth(-26db) <100KHZ MAX Frequency stability +/- 20PPM Modulation method AM Output power 80DBuv/m Reference oscillator A 27.145MHZ crystal oscillator is used to generate ths reference frequency It has a stability of +/-20ppm Amplifier Ths Oscillator is followed by amplifiers.These final output is 80dbuv/m max Microcontroller The tx system iscontrolled by a encode ic running with <300khz Oscillator
