Hello Everyone;
I want to use an RF choke for a gain block in 4.3GHz. What is the best value that I should use?

Is it for bias feed? A lumped element choke may perform well at 4.3 GHz. Use a quarter wavelength long high Z transmission line and one or two radial stubs instead.
Look at the manufacturer data sheets. Small chip inductors (0402 or 0603 size) of 10 to 20 nH have their parallel resonance
frequency in the said range. They provide perfect isolation. Murata's wirewound LQW series has highest resonant frequencies.
