Abstract
1,094,459. Parametric amplifiers. MULLARD Ltd. Aug. 26, 1966, No. 38306/66. Heading H3B. In a parametric amplifier two varactor diodes, each series resonant at the idler frequency, are connected together in series-aiding relationship to form a closed loop in which, at the idler frequency, each diode completes the series resonant circuit of the other. Preferably the diodes are connected together by a transmission line one half wavelength long at the idler frequency so that the assembly is resonant at the idler frequency. The centre conductor G of the signal input coaxial line is connected to the mid-point of conductive strip H, which forms part of the transmission line, so that the loop is balanced at the idler frequency. In one arrangement the larger diameter end of one diode rests on the bottom of waveguide W and the narrow end is recessed in strip H, while the larger end of the other diode is recessed in strip H and the narrow end is recessed in the bottom of the waveguide. The body of the latter diode is spaced from the bottom of the waveguide so that diodes are situated symmetrically within the waveguide. In a modified arrangement both diodes are recessed equally in the adjacent members.
