An asymmetrical spurline filter (ASF) with dual‐bandgap characteristics is designed and applied as the load network of the class‐E power amplifier to improve the output power and efficiency. Meanwhile, an equivalent circuit model is built for the proposed ASF based on two LCR resonators. © 2010 Wiley Periodicals, Inc.
