- This paper presents a broadband Switch-Mode Power Amplifier (SMPA) using a Band-Pass Filter (BPF) at the Output Matching Network (OMN). The proposed SMPA integrates a microstrip BPF as an output impedance matching network to significantly reduce the final circuit size. The microstrip lines of the filter simultaneously play the role of filtering and impedance matching. This proposed method reduces the size of the PA and reduces the power dissipation as much as possible. The BPF is placed at the output of the circuit using microstrip lines and the RT Duroid 6006 substrate. This BPF covers a wide bandwidth ranging from 3.0 GHz to 4.4 GHz. Simulation results show 9-14 dB gain with 44 - 56.6 % drain efficiency ( DE %), and the output power of 39 – 41.3 dBm would be achieved across the frequency band from 3.0 GHz to 4.4 GHz.
