Pll Fm Transmitter Schematic. This circuit will explain the pll controller unit for the fm transmitter it is very important since the transmitter frequency is digitally controlled and thereby very stable. 3672 hz at the antenna.
However unless you know how to build a serial data link and connect this lpfm transmitter to a pc or a microcontroller you won t be able to use the pll. The pll transmitter exciter has the functions of providing a stable low noise frequency selectable rf signal and amplify it to a controllable output power sufficient to drive the power amplifier. This phase locked loop keeps the generated signal and reference signal in a fixed relationship.
