摘要：
A communications device may include a power amplifier having an input and an output, and a direct current (DC) feed network. The DC feed network may include a radio frequency (RF) transmission line stub having a first end coupled to the output of the power amplifier and a second end coupled to a DC feed voltage, and at least one RF shorting switch coupled between a corresponding location along the RF transmission line stub and a voltage reference. The communications device may further include a controller configured to selectively operate the at least one RF shorting switch to set an operating frequency band of the power amplifier.
