【摘要】 报道了全平面C波段功率单片放大器及四单片合成放大器研究结果。单片放大器采用全离子注入工艺，均匀性好，平均成品率40％，可靠性高。工作频率4．7—5．2GHZ，中心频率5．0GHz处输出功率2．5W，增益15dB，功率附加效率31．5％。单片放大器芯片面积2．8mm×2．0mm，四路合成的4×MMIC频率范围不变，中心频率4．95GHz处输出功率8．2W，增益13dB，功率附加效率26％，四路合成效率接近80％。实验结果与理论预测基本吻合。更多还原

【Abstract】 A two-stage C-band power amplifier MMIC has been designed andfabricated by using ion-implant technology. The MMIC delivers power of 2. 2-2. 5W with gain of 15 dB over the band of 4. 7-5. 2 GHz. Power-added efficiency (PAE)is 31. 5% at 5. 0 GHz. The chip size is 2. 8 mm×2. 0 mm. An amplifier consisted ofsuch four MMICs parallelly connected by using Wilkinson divider/combiner offersoutput power of 7. 2-8. 2 W with gain of 13 dB in the frequency range of 4. 7-5. 2GHz and PAE of 26% at 4. 95 GHz.更多还原
