摘要/Abstract

摘要：

为了解决微波光子混频系统的非线性失真和动态范围受限问题，提出了一种基于并联双平行马赫-曾德尔调制器（DPMZM）的大动态范围微波光子混频系统。利用DPMZM实现射频和本振信号的并行调制，通过配置并行两路的电光调制指数及调制器的工作点，抵消输出中频信号中的三阶交调失真（IMD3），最终提高系统的动态范围。仿真结果表明，所提方案可将IMD3抑制17.7 dB，系统无杂散动态范围提高到 $127.8 dB \cdot {Hz}^{\frac{4}{5}}$ 。

Abstract:

To solve the problems of nonlinear distortion and limited dynamic range of microwave photonics mixing system, a large dynamic range microwave photonics mixing system based on parallel dual parallel Mach-Zehnder modulator (DPMZM) was proposed.The parallel modulation of radio frequency and local oscillator signals was realized by using DPMZM.The third-order intermodulation distortion (IMD3) in the output intermediate frequency signal was eliminated by configuring the electro-optic modulation index of the two parallel channels and the working point of the modulators.Finally, the dynamic range of the system was improved.Simulation results show that the proposed scheme can suppress IMD3 by 17.7 dB and increase the SFDR to $127.8 dB \cdot {Hz}^{\frac{4}{5}}$ .

Key words: microwave photonics, mixer, dynamic range, parallel DPMZM
