switch circuit at 2GHz?

Hi, everyone. I have a question about the switch circuit at 2GHz for antenna arrays.

What types of switch devices I should use at this frequency range, PIN diode, FET or anything else?

The other question is that: are there any specifications to design the low-frequency control circuits on the PCB?

Any references or books are appreciated, thanks.

check the switches of CEL

or u want to make a discrete solution
