Design of a compact 2.4 GHz class-F power amplifier (PA) with high power-added efficiency (PAE) using a novel harmonic control circuit (HCC) is reported. The main aims of the proposed PA are to obtain compact size and high PAE. The proposed HCC consists of an input matching circuit, a lampshade compact microstrip resonant cell (LCMRC) and output matching network (OMN). The HCC input matching circuit is employed to reduce the capacitive and inductive effects of the transistor. A part of the input matching circuit is replaced with a LCMRC to have more suppression at the third harmonic (7.2 GHz). The HCC OMN consists of two transmission lines for matching fundamental harmonic. The optimum values of the circuit parameters are obtained by harmonic balanced analysis at a drain voltage of 3 volts. The measured values of PAE and output power at 2.4 GHz are 83% and 23.65 dBm, respectively under 10 dBm input power. Furthermore, the fabricated amplifier occupies an area of 45 × 35 mm2 only.
