Abstract
Power amplifier systems including field trapper structures are disclosed. In embodiments, the power amplifier system includes a printed circuit board (PCB), a power amplifier module (PAM), and a field trapper structure. The PAM includes, in turn, a topside radio frequency (RF) input terminal, topside RF output terminal, a PAM topside surface on which the topside RF input terminal and the topside RF output terminal are located. The PAM is mounted to the PCB in an inverted orientation such that the PAM topside surface is positioned adjacent and faces a module mount region provided on a frontside of the PCB. The field trapper structure includes a first field trapper patch, which extends parallel to the PCB frontside, is composed of an electrically-conductive material, and is located within or adjacent the module mount region in the thickness direction.
