Abstract

A driver circuit for a power amplifier of a radio base station. The driver circuit comprises a radio frequency input, an output for connection to a power amplifier, a combiner connected to the radio frequency input and a first bias leg. The first bias leg comprises a bias source input, a first capacitor leg and a second capacitor, wherein the first capacitor leg is connected between the combiner and ground, and the second capacitor is connected between the combiner and ground. The first capacitor leg comprises a first switch and a first capacitor, the first switch being provided between the combiner and the first capacitor such that, in a first state, the first capacitor is connected to the combiner and, in a second state, the first capacitor is disconnected from the combiner. A corresponding power amplifier assembly, radio base station and method are also presented.
