Abstract

This paper presents a 24-30 GHz broadband Doherty PA (DPA) in Infineon 0.13 μm SiGe BiCMOS technology. A broadband transformer-based impedance inverter matching network (IIMN) is proposed and implemented to achieve simultaneous wide bandwidth and high efficiency within a compact size. Furthermore, a stacked PA unit cell topology is applied for power added efficiency (PAE) enhancement. In the 5G NR FR2 64-QAM modulated measurement from 24-30 GHz (5G N257 N258 bands) with 5% EVM constrain, this DPA achieves a maximum 17.24 dBm Pavg and 16.8% PAE with 100MHz BW. With 200 MHz BW, the maximum Pavg is 16.94 dBm, and PAEavg is 16.6%. With 400 MHz, the maximum Pavg is 15.37 dBm, and PAEavg is 14.6%. In 24-30 GHz (N257 N258), this PA could deliver above 12 dBm average output power (Pavg), and its average PAE (PAEavg) keeps higher than 10% in whole bands, all reported at critical 85C condition.
