Abstract
AbstractOne dual‐band high‐efficiency power amplifier (PA) based on a D‐CRLH structure is presented. The D‐CRLH cell is employed to realize one dual‐band second harmonic trapping for the two operation frequency bands. Based on above design strategy, high PA efficiency at two frequency bands can be achieved by transferring the fundamental and second harmonic impedances to appropriate positions on the Smith chart. For demonstration, one prototype is designed at 2.3 and 3.5 GHz by using the proposed design strategy. The results indicate one peak output power of 40 and 40.8 dBm at the measured frequency of 2.2 and 3.2 GHz, respectively, while the maximum power‐added efficiencies (PAE) are 73.9% and 64% at the two frequencies.
