Why FET works better as an RF amp than BJT?

 

[vfone]

FET’s have input impedance more constant under varying drive levels, better stability, better high order IMD, easier to broadband.

 

[flatulent]

They are also do not have thermal runaway or stored charge problems when they go into saturation.

 

[quangt]

Also, market favour

 

[Bhanumurthy]

Less noisy than BJT and one of the important requisites for front-end of a receiver.

 

[penghan]

Better linearity
