QUASI-BROADBAND AMPLIFIER ACCORDING TO THE DOHERTY PRINCIPLE

摘要

An amplifier has a first amplifier circuit (16), a second amplifier circuit (17), a hybrid coupler circuit (18) and a termination (1). The hybrid coupler circuit (18) has an output connection (13) and an insulation connection (12). The termination (1) is connected to the insulation connection (12) of the hybrid coupler circuit (18). The termination (1) comprises a first switch (30), a first capacitor (37) and a first inductor (31, 32, 33).
