1.5 nH to 300 nH Spiral Inductor Coils for Microwave Applications

SemiGen has introduced a series of spiral inductor coils for Microwave Applications up to 20 GHz. The inductors are available in ten models with seven different square dimensions including .030” x .030”, .040” x .040”, .045” x .045”, .055” x .055”, .065” x .065”, .075” x .075”, and .085” x .085” - all inductors are .012” thick. They have an inductance of 1.5 nH to 300 nH with 1.5 turns to 18.5 turns.

The SemiGen spiral inductor coils are manufactured on a thin film process on quartz substrates with precision photolithography and non-chemical etching to ensure clean edges and uniformity from coil to coil. A polymide coating is applied on the quartz substrate to eliminate the need for conformal coating or staking, inductors can be epoxied down with nonconductive epoxy and wire bonded for connection. These inductors are ideally suited for microwave circuits and power supplies.

Key Features:

  • No need for “Staking” Coil
  • Passivated Protective Coating Over Coil
  • Dimensional Uniformity
  • Planar Solid Structure Coil


For use in Attenuators, Amplifiers, Switches and Filters in replacement of conventional wound coils. Operating frequency is up to 20 GHz.
