This paper presents a simulation related to phase signal leakage in an improved Kahn based modulator for a high efficiency power amplifier. It contains a mathematical modeling of a leaked phase signal, an EVM simulation versus leakage, and a validation of the simulation method through comparison with measurement results. These are done using a LTE signal which has a bandwidth of 10 MHz, a PAPR of...
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...
