Overview
The HMC440QS16GETR, produced by Analog Devices Inc., is an integer-n synthesizer designed for high-frequency applications. This component integrates a 10 to 1300 MHz digital Phase-Frequency Detector and a 10 to 2800 MHz 5-Bit Frequency Counter. It is packaged in a miniature 16-lead QSOP plastic package, making it suitable for a variety of high-performance RF and microwave systems. The HMC440QS16GETR is particularly noted for its ultra-low phase noise floor, which enables synthesizers with wide loop bandwidth and fast settling times, resulting in very low phase noise.
