低失真超高频线性中功率晶体管
Low-Distortion UHF Linear Middle Power Transistors
【摘要】 叙述了主要用于UHF频段CATV主电榄放大器的高增益、低失真、线性中功率晶体管的设计和实践。在对晶体管失真及增益与器件参数研究的基础上,给出了低失真晶体管的最佳设计,并使3DA300晶体管在IM3=-60dB时Pout≥110dBμv,在500MHz时|S21e|2(?)10dB。
【Abstract】 Describes the design and experimental results for high gain and low-distortion UHF linear middle power transistors, used in UHF CATV main cable repeater. Based on researching the dependence on the distortion and gain on device paramaters, Optimum design for Low-distortion transistor is decribed. Transistor 3DA300 succeeds in achieving satisfac tory performances If IM3= -60dB, output power level Pout≥ 110dBμv,. Also insertion gain for |S210 |2 =10dB at 500MHz is obtained.
