A High-Power SOI-CMOS PA Module with Fan-Out Wafer-Level Packaging for 2.4 GHz Wi-Fi 6 Applications

This paper presents the first high-power SOI-CMOS power amplifier (PA) embedded in a Fan-Out Wafer Level Package (FOWLP) and addressing 2.4 GHz Wi-Fi 6 applications. At 2.44 GHz, the PA delivers 35.1 dBm of saturated output power (P

) with 53% of peak PAE and 29.5 dB of power gain. Without DPD, the PA achieves state-of-the art measured performance with 26.5/24.5/21.9 dBm of linear output power (P
out
) for an EVM (Error Vector Magnitude) of −30/−35/−43 dB with an operating current of 336/270/210 mA for MCS7/9/11 40MHz signals respectively. The PA shows robust operation under extreme load mismatch (8:1 VSWR) and temperature (-40 to 80°C) conditions.
