Overview
The HMC440QS16GE is an integer-n synthesizer produced by Analog Devices Inc. It is designed for use in low phase noise offset synthesizer applications, offering high frequency operation and an ultra-low phase noise floor. This component is particularly useful in systems requiring fast settling times and very low phase noise. The HMC440QS16GE can be used in conjunction with a differential loop amplifier to phase lock a Voltage-Controlled Oscillator (VCO) to a reference oscillator.
