I am going to use HMC322LP4E as SP8T RF switch at ~5G band.
There is VEE: -5 Vdc requirement for the switch,
Any recommendation of RF LDO to provide -5 Vdc?
Please take a look at Switched Capacitor Converters from Analog Devices. ADM8828/ADM8829 might be a good fit if you have 5V supply available on your system.

You will also need to use a driver circuit for voltage conversion at each control inputs of HMC322 if you only have positive control voltages. Our suggested driver circuit is below.
Thanks for your suggestion !!
