摘要
采用低温共烧陶瓷（LTCC）技术，设计制作了一种新颖的压控振荡器（VCO）。通过单电路结构，建立内埋螺旋式（Helical）结构电感和耦合电容模型，调整VCO匹配电路。测试结果表明，VCO输出频点为2．0～2．1GHz，相位噪声为-77dBc／Hz@10 kHz，输出功率为3dBm。外形尺寸为10mm×10mm×1mm，远小于传统印制电路板（PCB）基板VCO体积，适应系统小型化趋势。
A novel VCO （voltage control oscillator） was designed and manufactured by LTCC technology, through a three-dimensional structure with passive components embedded in substrate. The models of embedded helical inductors and coupling capacitors which were helpful matching circuit were established by single circuit configu ration. The output frequency of the LTCC VCO is 2.0-2.1 GHz,phase noise was --77 dBc/Hz@10 kHz,output power was 3 dBm, the outline dimensions were 10 mm×10 mm × 1 mm, which were far less than the traditional VCO on PCB substrate , accommodating with the miniature tendency.
