Question about HMC632LP5E and HMC736LP4E

We have some questions about the HMC632LP5E and the HMC736LP4E.

We would like to get only the 7.5GHz output using RFOPUT/2 function setting Fo=15GHz. We would not like

3.75GHz (RFOUT/4) in this case.

 

- HMC632LP5E

  In order to get only 7.5GHz output, the RFOUT and the RFOUT/4 pins will be terminated.

  Also the Vcc(Dig) pin will be open to stop the prescaler for RFOUT/4.

  We will use only the RFOPUT/2 pin. In such case, Fo/4 harmonics(3.75GHz) will appear from the RFOUT/2 pin?

  If yes, what is the ouput power of the Fo/4 from the RFOUT/2 pin?

  Is it 25dBc written in the datasheet?  (Harmonics/Subharmonics: 1/2 25dBc typ)

  Fo/8 harmonics will also appear?
