There are a lot of RF PA application notes using quarter-wave line for bias network. I wonder how I can use it for wide band PA design? Anyone can help me with this?
For wideband PA input/output matching, I guess the performance is compromised because you can get one layout optimal for wideband, right? So how do you start a match network design when you look at datasheet and find Zload and Zsouce dispersion a lot in smithchart.
