本文叙述了一个全固体化的不用调谐的60瓦2～30兆赫宽带线性放大器的设计、制造及其性能。其工作电压为28伏直流电,在60瓦未滤波输出时,其连续波(工作)总效率大于47%。放大器在60瓦峯值包络功率输出时,其双纯音效率大于31%。在输出功率为5～60瓦时,在该频段上的双纯音线性为一30分贝或优于一30分贝。阻抗匹配是通过绕在铁氧体环上的宽带传输线变压器来实现的。采用相同结构的混合电路来提高输出功率。 This article describes the design, manufacture, and performance of an all-solid, un-tuned, 60-watt, 2-30 MHz, broadband linear amplifier. Its operating voltage is 28 volts DC and its continuous wave (operating) total efficiency is greater than 47% at 60 watts unfiltered output. Amplifier at 60 watts peak envelope power output, its double pure sound efficiency is greater than 31%. At output powers of 5 to 60 watts, the double-pure linearity in this frequency band is either a 30 dB or better than a 30 dB. Impedance matching is accomplished by a broadband transmission line transformer wound around the ferrite ring. Use the same structure of the hybrid circuit to increase output power.
