We will present our efforts towards building a Josephson-junction-based TWPA that utilizes nonlinearities not only for amplification but also to upconvert backward propagating modes to a frequency band that can be easily discarded, effectively providing reverse isolation. This should help in improving the noise performance of the amplification chain while making it compact and better suited for upscaling the multiplexed measurement setups.
