“…To verify this idea, it is necessary to add package factors before the output matching circuit due to the existence of transistor encapsulation parameters [10]. A low-pass step impedance filter model, which consists of several high and low impedance microstrip lines, is used to be the output matching circuit.…”

Abstract:In this letter, a method for widening impedance matching spaces of power amplifier is proposed by expanding the voltage and current equations of class F power amplifiers. The proposed method can improve design flexibility and convenience of broadband power amplifiers while maintaining high output power and drain efficiency. To verify this theory, a power amplifier from 1 GHz to 3.5 GHz is designed. The measured experimental results show that the drain efficiency can reach 50.6%-63.4%, the output power is greater than 40 dBm, and the gain is greater than 10 dB.

“…4 shows the wideband output matching network [8] used for this design and the impedance trajectories in the Smith chart. The parasitic components are de-embedded based on the approximated network [9] of the CGH40006P. It can be seen that the fundamental and the second harmonic impedances are mostly in the region shown in Fig.…”

In this paper, a C-band wideband power amplifier (PA) using a GaN HEMT is proposed. The general Class-J mode, which offer a bigger design space for the fundamental and harmonic terminations, is introduced to implement wideband PA. Then, to verify the mechanism mentioned above, a wideband PA operating from 3.5 to 6.0 GHz is proposed and fabricated. Meanwhile, the load/source harmonic and baseband impedances are also considered for the linearity. The amplifier exhibits 8-11 dB gain and 51%-64% drain efficiency (DE) covering from 3.5 to 5.5 GHz.
