Abstract
An apparatus is comprised of a processor, a fast-locking Phase-Locked Loop Waveform Generator (PLLWG), an amplifier circuit, and a voltage controlled oscillator (VCO). The processor generates data program signals to program the PLLWG and generates a trigger command signal instructing the PLLWG to generate an analog tuning signal. The PLLWG, coupled to the processor, generates the analog tuning signal based on the trigger command signal. The amplifier circuit, coupled to the PLLWG, receives the analog tuning signal, amplify the analog tuning signal, and generates a control voltage. The VCO, coupled to the amplifier circuit, receives the control voltage and amplifies the control voltage to generate an amplified Radio Frequency (RF) channel frequency signal.
