Power amplifiers consist of an active device, biasing networks and input and output reactive filtering and transforming networks. These networks are effectively bandpass filters offering the required impedance transformation. They are also designed to offer some frequency shaping to compensate for the roll-off in the active device frequency response if broadband operation is required. However the function of each network is quite different. The input circuit usually provides impedance matching to achieve low input return loss and good power transfer. ...
