220-GHz High-Efficiency Power Amplifiers in 250-nm and 130-nm InP HBT Technologies Having 14.4-25.0% PAE and 40-60 mW $\mathrm{P}_{\text{out}}$
Abstract: We report two 220-GHz solid-state power amplifiers (PA, SSPA) having high output power $(\mathbf{P}_{\mathbf{out}})$ and record power-added-efficiency (PAE). The first amplifier (PA-1) uses ...
