Abstract:

Effort continued on the development of two experimental models of a low noise parametric amplifier.. The first amplifier was an untuned amplifier, broadband from 4000 to 6000 mc, and the second amplifier was electronically tunable from 4000 to 6000 mc. For the broadband amplifier, a micr wave circ it as constructed that simultaneously resonates the diode at the center signal and the center idler frequencies. This circuit, however, reduces the available signal and idler circuit bandwidths by 30. The experimental diode self resonant frequency was lower than the theoretical resonant frequency determined from the diode capacitance and the manufacturers specified lead inductance. This reduced the available idler circuit bandwidth. Schemes to achieve an electronically tunable amplifier were reviewed. The optimum scheme was to develop a wideband signal circuit, a narrowband idler circuit and use a backward wave oscillator to drive a broadband pump circuit. Author
