<p>PURPOSE: An apparatus for detecting PIM defect point of a electric wave wire using a phase is provided to accurately recognize the position of defective RF passive device or module. CONSTITUTION: An apparatus for detecting PIM defect point comprises: a phase detector(28) which receives each signal which is noise-filtered in a first receiving filter unit(26) and a second receiving filter unit(27a,27b); a PC which performs an operation process according to the phase and displays the site of PIM(passive Inter-modulation) defect point on a screen.</p> |
