Factors to consider in wireless signal amplifiers

There are many factors to consider when making wireless signal amplifiers, such as: printed circuit board materials, grounding schemes, interstage matching/input and output impedance matching, transient stability and thermal processing, etc., but also pay attention to transient stability issues, high-gain multi-stage amplifiers are vulnerable to feedback, in addition to the power transistor collection of power junctions need to dissipate a lot of power, dissipating power as heat, so we must do a good job in the production of wireless signal amplifiers such as thermal design.
