Phase Detector

HI,

We have requirement of Phase Detector for their TR Module of Surveillance Radar.

Frequency Range – 60 MHz to 4.0 GHz ( or min 3.5 GHz) in Pulse Modulation with Input signal at 10dbm..

Please help to know the suitable part in the application.

Regards,

Sai

  • Hi Sai,

    I'm not aware of a Phase Frequency Detector (anywhere) with a higher input frequency than the ones I recommended. You can consider adding a prescaler before the HMC469 or HMC3716 to reduce the input frequency and keep 'N' small or consider using the HMC698 or HMC699 PLL's which will accept a 7Ghz input and have a phase detector output or perhaps the HMC983LP4E and or HMC984LP4E may work. 

    If you need a 'phase detector' (as opposed to a phase frequency detector which is designed specifically for synthesizer applications) you should use a mixer instead. Perhaps the HMC129 could work?

    Please refer to FAQ: HMC Phase Frequency Detectors  for additional information.

    Best Regards,

    Marty
