Abstract

The IC stripline, an IEC radiated electromagnetic susceptibility (EMS) method, is utilized for evaluating the injection pulling and locking effects of the voltage-controlled oscillator (VCO). An IC stripline with the bandwidth of 2.5 GHz is realized and the test setup is built. A commercial VCO is tested for demonstration. Another IEC conducted EMS test, direct power injection, is also performed for comparison. The results show the effectiveness of characterizing injection pulling and locking of VCO by using the proposed solution.

用IEC电磁敏感性试验评价压控振荡器的注入拉锁

采用IEC辐射电磁磁化率(EMS)方法——IC带状线，对压控振荡器(VCO)的注入牵引和锁定效应进行了评价。实现了带宽为2.5 GHz的集成电路带状线，并搭建了测试装置。对商用VCO进行了演示测试。另一个IEC进行的EMS测试，直接功率注入，也进行了比较。结果表明，该方法可以有效地表征压控振荡器的注入拉拔和锁紧特性。
