amplifier bias circuits

[has_ajam]

I want to know what componenet should I use in bias circuits of LNA and Power Amps?

 

[dingjingfeng]

most of the time bandgap circuits, you can consult many paper

 

[has_ajam]

I mean discreate componets such as resistors and capacitors and their places
please upload papers

 

[dingjingfeng]

if you use a resistor, in serial please, and add a large capacitor between the other side of the resistor and ground.

 

[want to know]

inductor(or micstrip) , resistor, cap
the bias circuit is to provide DC for trasistor, and cannot influence the RF.
