This paper presents a broadband Doherty power amplifier (DPA) design with two continuous Class-F-1 matching circuit eliminating offset line in carrier way to increase the bandwidth and efficiency. By employing this compact and highly efficient design method, a DPA working at 2.0 GHz∼2.6 GHz is designed and implemented for verification. With continuous wave (CW) measurements, the experimental results...
This paper proposes multi-mode transferred power amplifier design. Several discrete frequency points, along with their second and third harmonics are controlled simultaneously by a special output matching network in PA. It allows the PA to transfer its mode to different typical high efficiency classes in these deliberately selected frequencies, which are referred to LTE and 3G systems. The measurement...
