摘要：

介绍了HL-2M装置低混杂波系统中3.7GHz微波激励源的设计。微波激励源设计为模块化形式，由 3.7GHz点频固态源单元、功率分配器单元、功率放大器单元和现场控制器单元等组成。微波激励源有8路输出端口，每个端口的输出功率在0~10W范围内连续可调，并可以实现远程控制输出功率；采用取样鉴相锁相环技术使微波输出信号具有相位噪声低、频率稳定度高、杂散抑制好等优点。频偏1kHz时，相位噪声是-115dBc/Hz，频偏10kHz 时，相位噪声是-117dBc/Hz，频偏100kHz 时，相位噪声是-122dBc/Hz；输出频率稳定度≤ 0.03ppm/30min；杂散抑制≤-80dBc。

Abstract:

The design of 3.7GHz microwave exciter for LHCD is presented. The system is composed of 11 modules: the single frequency solid-state source, the power divider, the power amplifier and the controller. There are 8 outputs in the microwave exciter, each output power range is within 0~10W and can be controlled continuously and remotely. The sampling phase detector and the phase-lock loop are used in the microwave exciter so the low phase noise, high frequency stability and high spurious rejection ratio of the microwave output signal can be realized. The phase noise are -115dBc/Hz at 1kHz, -117dBc/Hz at 10kHz, -122dBc/Hz at 100kHz, the frequency stability is ≤0.03ppm/30min and the spurious rejection ratio is ≤-80dBc.

Key words: LHCD, Microwave exciter, Sampling phase, Expansion capturing circuit, Phase noise
