چکیده
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.
