Hello I'm RF engineer.
I'm using HMC321 to divide RF band.
When I change the path RF1 to RF2, It need some delay time.
It doesn't mean switching time, the time is reaching final value of settling time 0.05dB(98.86% of the final value).
Now. I can not find about this information, it would be GaAs gate lag...
But I'm not sure. If It has gate lag, It would be less than 1ms.... but this time needs more than 300ms and power variation is more thean 0.1dB.
I captured image file. I don't know why this time delay is happend.
Let me know, If you know about this information.
