Product Attributes

Introduction

The HMC440QS16G(E) is an Integer-n synthesizer that incorporates a 10 to 1300 MHz digital PhaseFrequency Detector with 10 to 2800 MHz 5-Bit Frequency Counter (continuous division from 2 to 32) in miniature 16 lead QSOP plastic packages. It is intended for use in low phase noise offsetsynthesizer applications. The HMC440QS16G(E)’s combination of high frequency operation along with ultra low phase noise f loor make possible synthesizers with wide loop bandwidth and low N resulting in fast settling and very low phase noise. When used in conjunction with a differential loop amplif ier, the HMC440QS16G(E) generates an output voltage that can be used to phase lock a VCO to a reference oscillator.

Features

• Ultra Low SSB Phase Noise Floor: -153 dBc/Hz @ 10 kHz offset @ 100 MHz Reference Frequency.

• Open Collector Output Buffer Amplif iers for Interfacing w/ Op-Amp Based Loop Filter
• QSOP16G SMT Package: 29.4 mm²

Applications

• Satellite Communication Systems
• Point-to-Point Radios
