Its output frequency is locked to 96MHz using the phase-locked loop approach. Fig. 1: Author’s prototype wired on a copper clad sheet Circuit and working. The author’s prototype of the high fidelity ...

PLL FM Transmitter Circuit. April 20, 2009 by P. Marian ... so that the output power of the Phase-Locked Loop transmitter can be controlled from zero to 4 W by adjusting this voltage from zero to 15V.

A Cartesian transmitter based on pulse width modulation, with the capability to drive a switched power amplifier, such as a Class D stage, is presented. A phase-locked loop based technique is proposed ...
