Abstract
The gain of a negative-resistance parametric amplifier is highly sensitive to pump power changes. If the pump generator is noise-modulated in amplitude, a consequent gain modulation appears. In the presence of strong out-of-band interfering signals this can cause the output signal-to-noise ratio to deteriorate. The simple formula to estimate this effect has been derived and numerical results presented.
