Novel simulation method and possibility of class-s power amplifier for LTE base station

This paper presents novel simulation method and possibility of class S power amplifier for LTE base station. A baseband signal with 9.7 dB Peak-to-Average Power Ratio (PAPR) is used to represent LTE signal, which is about top 12-percent of the PAPR statistics. The channel bandwidth of 10 MHz and carrier frequency of 890.88 MHz is used to represent prearranged LTE service in Korea. A Band-Pass Delta-Sigma Modulator (BPDSM) is used to generate a digital-like signal. A Gallium-Nitride (GaN) based Complementary Voltage Switched Class D (CVSCD) with this digital-like signal is simulated and shows 31 % PAE and 2 % EVM.
