A compact broadband class-E power amplifier design is presented. High broadband power efficiency is observed from 2.0–2.5 GHz, where drain efficiency ≫74% and PAE ≫71%, when using 2nd-harmonic input tuning. The highest in-band efficiency performance is observed at 2.14 GHz from a 40V supply with peak drain-efficiency of 77.3% and peak PAE of 74.0% at 12W output power and 14dB gain. The best broadband output power performance is observed from 2.1–2.7 GHz without 2nd-harmonic input tuning, where… CONTINUE READING
