ADF4351 Typical Maximum Frequency

Hello

Datasheet of ADF4351 states that the maximum frequency is  4.4GHz. However,considering typical samples and typical conditions, could it go @ 5GHz ?

Best Regards,

  • The part can operate up to about 4.5 GHz but normal operation beyond 4.4 GHz cannot be guaranteed and performance may become unpredictable.

    What are your system requirements (channel spacing, reference frequency)? The ADF4156 PLL is similar to the ADF4351 but it requires an external VCO. It will operate up to 6.1 GHz.
