Hermetically-sealed electrically-absorptive low-pass radio frequency filters and electromagnetically lossy ceramic materials for said filters |
摘要 |
An electromagnetically lossy liquid- or gas-tight fusion seal for use as a low pass radio frequency signal filter constructed as a matrix of glass binder and ferrimagnetic and/or ferroelectric filler. Metal cased electrical filters are made by reflowing the material to form fused glass-to-metal seals and incorporating electrical thru-conductors therein which may be formed as inductive windings.
