Abstract
An amplifier provides a first amplifier circuit (16), a second amplifier circuit (17), a first hybrid-coupler circuit (18) and a termination (3). The hybrid-coupler circuit (18) provides an output terminal (13) and an insulation terminal (12). In this context, the termination (3) is connected to the insulation terminal (12) of the hybrid-coupler circuit (18). The termination (3) comprises a first capacitor (34) and/or an inductance (35), which is disposed directly at the insulation terminal (12) of the hybrid-coupler circuit (18).
