摘要：In this article, we present the idea of a WiMAX based audio/video transmission. The data transmitter will transmit an audio/video signal, which will be received by the receiver side. The hardware of the data transmitter consists of a CCD camera and audio mic. The CCD camera will capture the image and give the analog video signal to a fixed filter of 12 MHz. The filter is designed in such a way that it can only pass a signal of 12 MHz and 4 KHz audio signal. The analog signal is given at the base of C1815 transistor, which will amplify this analog signal. To remove the unwanted signals, we have used capacitors. The amplified signal is then passed through a capacitor of capacitance 504 pf. the output signal at the capacitor is than pass through an RF amplifier. The RF amplifier will give strength and power to the signal. In RF amplifier section we have used a variable tuned circuit. The inductor used at the RF amplifier section act as antenna that will transmit the video signal and audio to the air.
