A Maximum Efficiency-86% Hybrid Power Modulator for 5G New Radio(NR) Applications

A hybrid power modulator is presented for the radio frequency (RF) amplifiers of 5th generation mobile communication technology (5G) new (NR) applications. utilizing a two-level switching converter and broadband high-efficiency linear amplifier presented. further improvement in efficiency circuit achieved by using an optimized supply voltage converters 4.5 V. In this way, overall improved more than 5% compared to 5 V voltage. The consists four stages. order improve bandwidth stability, compensation added that eliminates poles main introducing additional zeros, indirectly pushing pole distribution out bandwidth. Using approach, achieves 3-dB 180 MHz 51%. maximum output 2.4 W 86% when tracking 100 5G-NR signal under 4 Ω load nm CMOS package.
