Quesetion about HMC681A

Hello professor,

    In the datasheet of HMC681A, there is an index of relative phase vs frequency. Could you please explain, what relative phase is, for me? And the datasheet just list the applications of 50 to 350MHz tuning and 350 to 1000MHz.

If the signal I used is lower than 50MHz, what about the performance of HMC681A, especially its impact on the signal phase? If you can recommend other chips whose  impact on the signal phase relatively small, it would be great.

    Thanks for answering.
