I want to change ADF 4351 with hittite hmc833lp6ge PLL and my question is there is a Vvco and Zbias circuit between RF out of ADF 4350 and LO input of ADL 5375. Should I use same method for hittie PLL or not.....
The HMC833 offers single-ended output only so the ADL5375 will have to be driven in a single-ended fashion.
Install an AC coupling capacitor between the HMC833 pin 28 RF_OUT and the ADL5375 LOIP input.
ADL5375 LOIN input pin also needs a AC coupling capacitor to ground.
Moved this question on the HMC833 to the Hittite Microwave Products from ADI community.
Thanks DonY fro your help
