摘要：
The disclosure relates to a system and method for attenuating harmonics in a power amplifier. An electronic circuit for reducing leakage of radio frequency signals from a power amplifier of a wireless communication device is provided. The circuit comprises: a printed circuit board (PCB) having the power amplifier mounted on the PCB; a first electrical track in the PCB connecting to a power input terminal of the power amplifier; and a first capacitor connected to the first electrical track and a ground reference in the PCB, the first capacitor reducing transmission of radio frequency signals from the input terminal of the power amplifier.
