Class E microwave amplifier built on a SiC transistor with high on-state resistance
Theoretical and experimental investigations of a wide-band microstrip-design class E amplifier on a SiC MESFET have been performed with due regard for the transistor on-state resistance. The efficiency versus passband relationships obtained by experiments are in good agreement with the results of theoretical calculation.
