叙述了采用800兆赫集成电路工艺实现增益为20分贝和带宽为250兆赫的一种单片宽带放大器。在零分贝毫瓦信号电平下,二次和三次互相调制失真度分别低于-55和-42分贝(整个频带)。匹配端阻抗75欧姆,电压驻波比小于1.7。讨论了电路和工艺的设计以及电路性能的计算机最佳化设计。 Describes a monolithic wideband amplifier that uses an 800 MHz IC process to achieve a gain of 20 dB and a bandwidth of 250 MHz. At zero dB milliwatts, the second and third intermodulation distortions are below -55 and -42 dB respectively (the entire band). Matched end impedance 75 ohm, voltage standing wave ratio less than 1.7. The design of circuits and processes as well as computer optimization of circuit performance are discussed.
