Microstrip Transmission Lines

50-ohm Transmission lines offer a designer complete flexibility and repeatability for the most challenging RF and Microwave applications.

  • Characterized and ready for use right out of the box
  • All tabulated data includes > 3 skin depths of AU— loss and impedance specifications are Guaranteed!
  • Ion Milling Process creates vertical conductor walls with no undercutting and 100% repeatability so production results are guaranteed to conform to model test data
  • Suitable for Au/Sn and Au/Ge attachment
  • Metallization is 3-4 microns plated Au over Ti/Pt/Au sputtered seed layer both sides
  • Substrate is polished 99.6% alumina 

Microstrip Transmission Lines are available in thicknesses of 5 mil, 10 mil, 15 mil, 20 mil, and 25 mil with tolerances of +/- 1 mil.

W0 for various size substrates:

0.00463” for 0.005” Alumina
0.00957” for 0.010” Alumina
0.01433” for 0.015” Alumina
0.01920” for 0.020” Alumina
0.02446” for 0.025” Alumina

Ordering Information:

Our 50 Ohm Microstrip Transmission Lines are offered as individual items or can be purchased in assorted quantities through one of our convenient engineering kits.  Please contact us for pricing and details.  Microstrip Transmission lines are usually available within 2 weeks of order.

Transmission lines are available in a variety of lengths, widths, and substrate thicknesses.  Please see the tables below for ordering information and specifications.  If your needs require something not offered as a standard product, Ion Beam Milling can also fabricate custom transmission lines built to your specifications.  Please see our custom section for details.
