Patent ID: 8547171

Claim:
A printed circuit board (PCB) for an electronic circuit for a power amplifier of a wireless communication device, comprising: a substrate; a ground reference in the substrate; a first location in the substrate for placement of the power amplifier; a first pad in the substrate at the first location for a high band power input terminal of the power amplifier; a second location in the substrate for a battery terminal for the power amplifier; a first electrical track in the substrate providing part of an electrical connection from the first pad to the second location; a third location in the first electrical track for placement of a first capacitor in a circuit between the first pad and the ground reference; a second pad in the substrate at the first location for an output terminal of the power amplifier; a second electrical track in the substrate providing part of an electrical connection from the second pad to an output filtering stage circuit for the power amplifier; and a fourth location for placement of a 0 ohm component in the output stage, wherein the 0 ohm component, when populated in the output filtering stage, delays output signals from the output terminal; and the first capacitor provides part of a low pass filter to attenuate signals from the power amplifier to the battery.
