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.

This paper describes the architecture and circuit design of a low data rate FM-UWB transmitter. A Δ-Σ fractional-N PLL with a multi-phase relaxation oscillator is designed to enable sub-carrier ...
