We propose a phase-insensitive parametric amplifier featuring image cancelation and a doubly tuned transformer to enhance its bandwidth. Exploiting the reduced loss of passive components at cryogenic temperatures, the experimental characterization of a prototype shows a power gain of 9 dB with a bandwidth of 1.85 GHz for a pump frequency of 15.6 GHz and an image rejection of ~24 dB at 8.5 K. The amplifier consumes 33 mW in total at 8.5 K.
