Abstract
This article presents the design of a novel dual‐band signal cancellation circuit and its application to feedforward linear power amplifier. Intermodulation distortion cancellation loop shows 20.45 dB and 25.04 dB suppression for digital cellular band and IMT‐2000 band, respectively, over a correction bandwidth of 100 MHz. From the adjacent channel leakage ratio measurement, 16.5 dB and 18.6 dB improvements are achieved for each band under simultaneous operation. © 2009 Wiley Periodicals, Inc.
