Analysis of plastic material moisture absorption and dissipation characteristic for crystal rod holder design optimization

Crystal rod holders (CRH) are mounted in tunable filter microcircuits assembled inside the Signal or Spectrum Analyzer. Performance repeatability is an important criteria for the Spectrum Analyzer. CRH can be in varieties of design and materials to hold the different tunable filter microcircuit fre...
