Abstract
An RF power amplifier includes an input coupler including a first resistor and a first capacitor, an input phase difference network of the input coupler including a first input direct current (DC) bias injection network and a second capacitor connected in series with the first resistor. The second capacitor increases a bandwidth of the RF power amplifier. The RF power amplifier may further include a first power amplifier and a second power amplifier. The first input DC bias injection network provides power to the first power amplifier and the second power amplifier. The RF power amplifier includes a lateral dimension narrower than a lateral dimension of an RF power amplifier comprising bias circuitry on two opposing sides.
