In this paper, a modified class-F power-amplifier (PA) for GSM applications is designed,
simulated and tested. In this design, novel symmetrical meandered lines compact microstrip
resonant cell (SMLCMRC), is proposed as a new harmonics control circuit (HCC), which
resulted in size compression, power added efficiency (PAE) enhancement, power gain
improvement, and better linearization in the PA. In this work both of the conventional class-F
amplifier and proposed amplifier with SMLCMRC is designed at 1.8 GHz. The …
