摘要

有源锁模光电振荡器（AML-OEO）是一种高质量的脉冲微波源，可以产生各种形式的微波脉冲信号。我们介绍了一种用于产生双频微波脉冲的AML-OEO结构。在双频微波脉冲序列的情况下，每个子脉冲包含具有一对不同中心频率的信号。可根据不同场景的频带要求，选择不同的滤波器进行调整。所生成的双频微波脉冲信号在两种载波频率下均表现出良好的相位噪声性能，在6.55 GHz和10.79 GHz下可生成相位噪声分别低至- 120.9 dBc/Hz@10 kHz和- 120.5 dBc/Hz@10 kHz的脉冲信号。这种结构更简单、更紧凑，未来有望在多波段雷达、通信等领域发挥作用。

Generation of Dual-Frequency Microwave Pulse Based on Active Mode-Locked Optoelectronic Oscillator

Active mode-locked optoelectronic oscillator(AML-OEO) is a high-quality pulsed microwave source that can be used to generate microwave pulse signals in various forms. We introduce a structure for an AML-OEO, which is intended to generate dual- frequency microwave pulses. In the context of a dual-band microwave pulse sequence, each sub-pulse incorporates signals having a pair of distinct center frequencies. Different filters can be selected for adjustment according to the band requirements of different scenarios. The generated dual-band microwave pulse signals exhibit excellent phase noise performance at both carrier frequencies, we can generate pulse signals with phase noise as low as −120.9 dBc/Hz@10 kHz at 6.55 GHz and −120.5 dBc/Hz@10 kHz at 10.79 GHz. This structure is simpler and more compact, and is expected to play a role in multi-band radar, communications and other fields in the future.
