A Fully-Integrated Dual Band CMOS Power Amplifier Based on an Active Matching Transformer
摘要
Abstract
We propose a dual band CMOS power amplifier for mobile WiMAX systems. The power amplifier, combined with an active matching transformer, is fully integrated and fabricated in a 0.13μm CMOS process. The transformer operates at dual bands with active matching circuit. The measured result shows that the transformer efficiency of 78. 2% and 70. 4% at 2.5 and 3.5GHz are realized,respectively,and 26. 5 and 24.8dB gain are achieved. The PAE reaches 20% and 28% at 2. 5 and 3.5GHz,respectively. The third inter-modulation (IM3) is lower than-30dBc at the 25dBm average power.关键词
