Based on the UAV requirements of small airborne equipment, the paper discusses the necessity of using PCM-FM modulation method to design small airborne transmitter. It is also introduced the principle to complete transmitter design using direct PLL FM technology, given phase transmission model using of dual voltage-controlled ports of the VCO to achieve… CONTINUE READING
