摘要
基于LTCC技术,设计制作了一款小型化频率源。该频率源采用单环锁相电路实现,并将输出滤波器集成在LTCC基板内,实现了电路的小型化,锁相环电路板面积仅为20 mm×20 mm。同时给出了该频率源的组装及调试过程,经测试,该频率源输出频率为12.5～13.5GHz,相噪为-80 dBc/Hz@1kHz。
A miniaturization Frequency Synthesizer has been designed and fabricated using Low-temperature Co-fired Ceramic （LTCC） technology. The Frequency Synthesizer adopts monocyc!ie phase locked circuit, and output filter can integrate inside the substrate. It can realize the goal of miniaturization. The area of this frequency synthesizer is only 20ram x 20ram through proper arrangement. It also gives the process of Frequency Synthesizer assembly and adjustment. The output frequency is from 12. 5GHz to 13.5GHz, phase noise is - 80dBc/Hz@ 1 kHz.
