A wide-band monolithic amplifier is described which realizes 20-dB gain and 250-MHz bandwidth using an 800-MHz integrated-circuit process. At 0-dBm signal levels, second- and third-order inter-modulation distortion levels are below -55 and -42 dB, respectively, across the band. Terminal impedances are matched to 75 /spl Omega/ with VSWR better than 1.7. Both circuit and process design are described as well as computer optimization of circuit performance.
