Abstract: A microwave inductor including a coil with windings tapered from a first end of the coil to a second end of the coil to reduce resonant loss glitches found in conventional inductors which have uniform diameter windings. The coil further includes a core composed of a dielectric material containing a colloidal suspension of magnetic particles, the magnetic material preferably being iron powder and the dielectric preferably being epoxy, making the core a poly-iron material. The magnetic particles being colloidally suspended in dielectric increase the impedance of the coil at high frequencies to reduce resonant glitches without lowering the low frequency Q of the inductor. As such, a single coil can be utilized both in a filter which requires a low impedance at low frequencies to create a high Q, and as a bias line which operates at frequencies well beyond the resonant frequency of the inductor since a high impedance is provided by the core at higher resonant frequencies.

Abstract: An electrically conductive wire wound into a conical coil 1 with leads from the small and large ends of the coil. The coil is filled with fine-grained magnetic material 11, and is mounted in a thin-walled, electrically non-conductive carrier 21 designed for precise automated assembly onto a circuit board 15. The wire leads are plastic-welded onto the carrier, and no metallic pads are used, greatly increasing the effective bandwidth of the choke.

Precise coil positioning, minimal lead length, and a totally non-conductive carrier virtually eliminates electrical reflections and resonances to yield a broadband choke with exceptional frequency range.
