2.9 GHz Integer-N Synthesizer (N = 2 - 32)

The HMC4069LP4E is an Integer-N synthesizer which incorporates a 10 to 1300MHz digital phase-frequency detector with a 10 to 2900MHz 5-bit frequency counter. It is intended for use in low phase noise synthesizer applications.

The combination of high frequency of operation along with its ultra low phase noise floor make possible synthesizers with wide loop bandwidth and low N resulting in fast switching and very low phase noise. When used in conjunction with a differential loop amplifier, the HMC4069LP4E generates output voltages that can be used to phase lock a VCO to a reference oscillator.

The device is packaged in a 24-pin, 4 x 4mm leadless QFN surface mount package with an exposed ground paddle for improved RF and thermal performance.
