“…At present, most existing PAs related to the beautiful design and construction of buildings suffer from various limitations 12–43 . Harmonic controlled amplifiers are no longer applicable due to very little efficiency improvement as well as narrow bandwidth at mm‐wave band 12–14 .…”

“…Switched mode PAs require the power devices to keep fast‐enough switching yields and realize a zero loss on a period. Power combining amplifiers can enhance the output power, but its bandwidth and efficiency will be limited by the combined network 15–25 . Continuous mode PAs provide a wideband design theory by introducing larger impedance design space.…”

SummaryThis paper presents a broadband monolithic millimeter‐wave integrated circuit GaN power amplifier (PA) with arbitrary two‐port complex‐impedance matching method. The proposed matching topology has been applied to interstage matching network design by modifying traditional coupling matrix and synthesizing a desired network. The optimum load traction technique is introduced to provide some more suitable Zopts. After continuous‐wave test, the three‐stage MMIC PA achieves a peak PAE of 39.1% with a 34.9 dBm output power from 23 to 29.5 GHz and the measured S21 is 32.5 dB with a ±2.5 dB gain variation. When driven by a 400 MHz OFDM modulation signal with a PAPR of 8.5 dB, the measured ACPR is improved to −40.6/−40.7 dBc with DPD. In this case, the PA achieves an average PAE of 11.7% and a 26.7 dBm average output power.
