A novel miniaturized power amplifier with nth harmonic suppression
چکیده انگلیسی
In this paper, a novel miniaturized power amplifier (PA) matched by two proposed low pass filters (LPFs) with nth harmonics suppression is presented. In the proposed PA, the LPFs are employed as an output and input impedance transformer networks, which transform 50 Ω to the desired impedances. In the proposed PA the conventional output and input matching networks are eliminated, which results in 52% size reduction and 6% power added efficiency (PAE) improvement compared with the conventional PA. Moreover, using the LPFs at the output and input impressively suppress the unwanted harmonics (2nd-6th) with high level of attenuation. The proposed PA works at the 2.6 GHz, which is suitable for long term evolution (LTE) applications. The measured and simulated results are in the good agreement, which confirm the validity of the proposed method.
