Abstract

This paper presents a 24–30 GHz broadband Doherty P A (DP A) in Infineon $0.13 \mu \mathrm{m}$ 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 $\text{PAE}_{\mathrm{a}\mathrm{v}\mathrm{g}}$ is 16.6%. With 400 MHz, the maximum Pavg is 15.37 dBm, and $\text{PAE}_{\mathrm{a}\mathrm{v}\mathrm{g}}$ is 14.6%. In 24–30 GHz (N257 N258), this PA could deliver above 12 dBm average output power (P avg), and its average PAE $(\text{PAE}_{\mathrm{a}\mathrm{v}\mathrm{g}})$ keeps higher than 10% in whole bands, all reported at critical $8 5^{\circ}\mathrm{C}$ condition.
