For product with much tighter spacing requirements, etched thick film substrates are the best solution and are more cost effective.


  • Etched standard 2 mil lines and spaces (1 mil lines special request) on gold. Etched Gold Thick Film has better insertion loss at higher frequencies than comparable Thin Film RF circuits
  • Lange couplers available that do not require wire bonding to tie coupler elements together
  • Silver etching available
