提出了一种基于极化调制器的互补移频器（PCFS），并分别利用单循环和双循环移频环实现了锁频多载波的产生。从理论上研究了PCFS和基于PCFS的多载波发生器的传递函数和输出特性。基于我们通过VPItransmissionMaker软件的仿真结果，已经获得了100个稳定的载波，具有可接受的平坦度，而不需要直流偏置控制。结果表明，提出的PCFS有潜力成为一个商业产品，然后在各种场景中使用。
A novel polarization-modulator-based complementary frequency shifter (PCFS) has been proposed and then used to implement the generation of a frequency-locked multicarrier with single- and dual-recirculating frequency shifting loops, respectively. The transfer functions and output properties of PCFS and PCFS-based multicarrier generator have been studied theoretically. Based on our simulation results through VPItransmissionMaker software, 100 stable carriers have been obtained with acceptable flatness while no DC bias control is required. The results show that the proposed PCFS has the potential to become a commercial product and then used in various scenarios.
