Design of 35-dB 0.03-to-2.7 GHz Two-Stage Broadband Power Amplifier With 37.2 dBm P<sub>sat</sub> Using Modular Technology

A methodology for designing multioctave high-efficiency power amplifiers (PA) is presented in this letter. The sequential loadpull technique (SLPT) considering the second and third harmonic characteristics is proposed and combined with the multiple frequency matching theory (MFMT) to achieve outstanding performance in terms of operating bandwidth as well as efficiency. To verify the proposed theory, a 10 W GaN HEMT device is used. The proposed PA achieves a fractional bandwidth of 152% from 0.6 to 4.5 GHz. In such a wide frequency band, the drain efficiency (DE) is measured as 50% -68% with an output power of greater than 38 dBm and a large signal gain greater than 8 dB.
