A 5.9/26.5-GHz Dual-Band Concurrent Low Noise Amplfier for 5G NR C-V2X

초록

This paper presents a 5.9/26.5-GHz dual-band concurrent low noise amplifier (LNA) for 5G NR C-V2X. The proposed dual-band LNA is used cascode structure to implement similar gains in two distant frequency bands in a compact area and simple architecture. The dual-band matching circuit, which implements both input and output for a compact area, consists of an LC parallel circuit and a CLC pi network circuit. The measured S11, S22, S21, and NF were, -17.7, -9.2, 16.5, and 1.69 dB at 5.9 GHz, and -14, -12, 17.4, and 2.98 dB at 26.5 GHz, with 18mW under 2 V supply voltage, designed by using the 0.15-μm GaAs p-HEMT process © 2024 IEEE.
