The continuouswaveoutput from the PSK modulator 20 is delayed in delay circuits 26I and 26Q and is then supplied, as a reference signal, to each of mixers of a receiving mixer 30.
Under continuouswave pumping, backward amplified spontaneous emission output power (ASE-) rapidly increases to peak value, and then decreases monotonically to steady-state value.
在连续波泵浦下，反向自发辐射输出功率（ASE-）首先快速地增加到峰值功率，然后单调下降到稳态值；

The input and output use the standard rectangle wave-guide, the transition between rectangle wave-guide and fin-line is continuous gradual change line, and it has good capability of matching.
