Microwave inductor with poly-iron core configured to limit interference with transmission line signals |
摘要 |
An inductor coil is made with windings turns in a conical shape tapered from a very small diameter and gradually increasing. The core of the coil is composed of a dielectric material with a colloidal suspension of magnetic particles, i.e. poly-iron. The core functions to increase impedance at higher frequencies to reduce resonant loss glitches, while providing a low impedance at low frequencies to provide a high Q at low frequencies. The core can be part air (or non-magnetic dielectric) and part poly-iron, with the air portion provided closest to a transmission line where the inductor is connected to prevent the core from interfering with the magnetic field of signals on a transmission line.
