An Efficient Linearized Octave-Bandwidth Power Amplifier for Carrier Aggregation
In this paper, a single-stage octave bandwidth power amplifier from 2–4 GHz with greater than 10 W output power and drain efficiency ranging from 55–70 % is presented. Input and output networks are synthesized to match the fundamental, 2nd and 3rd harmonics for efficiency, based on load-pull simulations. The amplifier performance is characterized over the entire band for a 20-MHz LTE signal with a PAPR of 8 dB, demonstrating an average efficiency greater than 25 % with a normalized mean square error (NSMR) below −28 dB. Two 20-MHz signals are then simultaneously amplified with a spacing that varies from 200 MHz to 1 GHz, with resulting average efficiencies over 28%.
