Abstract

The design of high power push-pull amplifier and unique balun structure are presented. The balun consists of a dielectric resonator and slot line. In comparison with previous balun made up with cavity fixture by G.J. Laughlin (1976), the proposed one can be easily implemented due to its simple structure. The experimental result shows that push-pull amplifier has a gain of 13.7dB at the 2.1GHz W-CDMA band. With two carrier W-CDMA signal, the push-pull amplifier achieves an efficiency of 18.8% at the 41.5dBm average output power and ACLR test results of 36.7dBc at the 5MHz offset and 43.6dBc at the 10MHz offset.

介电谐振腔槽线平衡推挽放大器的设计

介绍了大功率推挽放大器的设计和独特的平衡结构。平衡器由介电谐振器和槽线组成。与G.J. Laughlin(1976)以前用腔夹具组成的平衡器相比，该平衡器结构简单，易于实现。实验结果表明，该推挽放大器在2.1GHz W-CDMA频段的增益为13.7dB。在双载波W-CDMA信号下，推挽放大器在41.5dBm平均输出功率下的效率为18.8%，在5MHz偏置和10MHz偏置下的ACLR测试结果分别为36.7dBc和43.6dBc。
