SMT Inductor(RF choke) with SRF about 3GHz

With reverse bias, the PIN diode looks like a capacitance. Resonate
that capacitance with a parallel inductor, and you'll do more for
isolation than you will by increasing the reverse bias from 5V to 40V.
I assume you're not dealing with signals that are several volts in
amplitude...
