Abstract:
1. A hybrid upconverter comprising: a low noise amplifier and a two port parametric amplifier, the two port parametric amplifier comprising a first port to receive an input signal to be amplified and upconverted and a second port to receive a local oscillator signal and to output an amplified, upconverted signal at upper and lower sideband frequencies; the parametric amplifier further comprising an antenna coupled to the second port to receive the local oscillator signal and transmit the amplified, upconverted signal at upper and lower sideband frequencies; the low noise amplifier driving the first port of the parametric amplifier; the two port parametric amplifier further comprising a pair of varactor diodes connected between the first port and the second port; and the diodes being connected in parallel from the first port and in series from the second port, and the low noise amplifier being connected directly to the pair of varactor diodes.
