Abstract :
A criterion has been found for developing broadband parametric amplifiers of either reflection or upconverter type which are capable of large bandwidths with a minimum of external circuitry. The method to be described depends on the maximum utilization of the parasitic elements (R/sub s/, L, C/sub o/, C/sub c/) of the varactor diode itself, plus certain simple experimental techniques which are easily applied. To illustrate the power of this method, a reflection type parametric amplifier has been developed with the following characteristics:
