I need disable/enable RF output of ADF4360-1 quickly, i.e. in less than 1 microsecond.
There is no single pin like "TXON" or "Output Enable". I don't see a way to access "MUTE" block either, which is driven by "Lock Detect" only (?).
My question is:
May I disable RF output by disconnecting RFoutA and RFoutB pins from DC supply?
In that case, all the tail current of the output differential pair transistors would flow probably through their B-E junctions; is it safe?
Any other suggestions how to mute RF output quickly?
Thanks in advance
