and for ultra low-noise microwave detectors employed in astrophysics. It consists of an only one wavelength small nondegenerate Josephson parametric reflection amplifier with integrated directionality. The device has two Josephson junction oscillators, connected via a tailored impedance to an on-chip passive circuit which directs the in- to the output port. The amplifier provides a gain of 20~dB over a bandwidth of 440~MHz and the total photon shot noise at the input corresponds to maximally ∼1.3 photons per second per Hertz of bandwidth. We predict a factor of four increase in dynamic range compared to conventional Josephson parametric amplifiers.
