Abstract:
A full Ka-band millimeter-wave power amplifier (PA) with magnetic coupling resonator (MCR) matching network is designed in this paper which is based on 65nm SOI CMOS process. Impedance transformation is performed by MCR to achieve broadband impedance matching. The technology of neutralizing capacitor and source degeneration inductance is adopted to effectively improve the circuit performance. The simulation results of the amplifier show that at 28GHz, the saturated output power (Psat) is 20.1dBm, the output power 1dB compression point (P1dB) is 18.3dBm, and the peak power added efficiency (PAE) is 31.2%. The small-signal gain of 21.4dB and the 3dB bandwidth of is 21.5-41GHz, with a fractional bandwidth of 62%, which can cover the entire Ka-band. © 2022 IEEE.
