Abstract:

Work was continued on a low noise broadband S-band reactance amplifier. A parametric upconverter fabricated in reduced height X-band waveguide was extensively tested. Results were negative and efforts were shifted to upconverters using a full height X-band waveguide. A number of diode mounts were te ted and parametric upconver ers using these mounts are currently being developed. The existence of a transmission passband for the mount-diode combination at the operating frequencies appe r as a necessary condition for broadband operation. The same broadband upconverter were operated as one-port circulator-coupled parametric amplifiers with performance comparable to that of the unconverters. The balanced 2-diode parametric amplifier has provided gain of 3-6 db over a 1400 mc band however, oscillations at some frequencies were observed. Si ce the balanced scheme yielded the most broadband performance, major efforts were devoted to this approach and efforts were limited to single-port experiments on those upconverter structures which have exhibited good gain and bandwidth as lower sideb nd upconvert rs.
