Possible to disable or shut down the Fo/2 RF path? This is because I am not using the path and would like to reduce the current.
If yes, what is the possible way?
No, unfortunately there is no way to power down the HMC508 divider. What frequency do you need to operate at?
There may be a more suitable VCO with similar operating range that does not have an RFOut/2 divider. Such as HMC506 which has a frequency range of 7.8 - 8.7 GHz. Typical operating current is 77mA.
