Abstract
In this article the behavior of continuous mode amplifiers at different reference planes is discussed using the example of a continuous class-F−1 amplifier mode. The variation of the output impedances and the conversion of the output voltage and current waveforms are analyzed depending on the considered reference plane. For instance, the frequently discussed current source reference plane has a way different impedance characteristic than the accessible lead reference plane. In order to study this aspect, a broadband continuous class-F−1 mode amplifier has been realized using a bare-die GaN-HEMT. From 1.0 to 1.8 GHz, this amplifier attains 44.5–45.2 dBm output power with corresponding drain efficiency of 65–68%.
