This paper presents a controllable mode design method for a concurrent dual-mode power amplifier (PA). The principle of the controllable mode combination is proposed by investigating the characteristics of different highly efficient PA modes, which is analyzed from frequency response of the low-pass matching circuit. Then a dual-mode PA with Class- and Class-J mode is taken for example...
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...
