C-BAND, WIDEBAND SOLID STATE AMPLIFIER
Abstract
A microwave circuit was developed for a fixedtunnel, broadband amplifier that reduces the diode lead inductance and simultaneously resonates the diode at the center signal and the center idler frequency with a minimum reduction in available bandwidth. Parallel tuned coaxial resonators were developed to multitune the signal circuit. A wideband single-diode amplifier was constructed with a bandwidth of 900 mc. The absolute gain of the one-port amplifier and circulator varied between 9 and 12 db over the 900 mc. The noise figure of the paramp-circulator varied between 2.9 and 3.1 db over most of the frequency range. A tuned single-diode amplifier was developed which can be swept in single frequency over an 800 mc frequency range with nearly constant amplifier gain and noise figure. A 1300 mc tuning range is also possible with a deterioration in noise figure. (Author)
