A Linear High-Power Reconfigurable SOI-CMOS Front-End Module for WI-FI 6/6E Applications

This paper presents a high-power monolithic SOI-CMOS Front End-Module (FEM) supporting Wi-Fi 6/6E signals at 2.4GHz. The FEM includes an SP4T antenna switch, a power amplifier (PA), a low noise amplifier (LNA) with bypass mode, and a digital controller. The RX path achieves 15dB of power gain with l...

Summary:This paper presents a high-power monolithic SOI-CMOS Front End-Module (FEM) supporting Wi-Fi 6/6E signals at 2.4GHz. The FEM includes an SP4T antenna switch, a power amplifier (PA), a low noise amplifier (LNA) with bypass mode, and a digital controller. The RX path achieves 15dB of power gain with less than 1.8dB of noise figure (NF) with 10mW of power consumption. The TX path delivers 33.4dBm of saturated output power (\mathrm{P}_{\text{sat}}) with 51.7% of peak PAE and 28.5dB of power gain. Without DPD, the reconfigurable TX path achieves state-of-the art performance with 23.4/20dBm of linear output power (\mathrm{P}_{\text{out}}) for an EVM of −35.1/−43.9dB and an operating current of 282/254mA for 802.11ac/ax MCS9/MCS11 40MHz signals.
