摘要：

In this work, we demonstrate a novel topology combining the large delays available in acoustic devices with parametric amplification to obtain non-reciprocal propagation of forward and reverse RF signal. The device can operate in a phase-coherent degenerate mode for an optimum gain of 12.7dB and an isolation of 18.3dB. In a degenerate phase incoherent mode, the device is capable of 3.1 dB of gain and 5.2 dB of isolation.
