Wire and ribbon bondable and Flipchip thick film
chip attenuators, printed and fired on 96% alumina.
Provides attenuation accuracy for frequencies
through 10 Ghz. Double layer terminations provide
additional bonding surface. Abrasive trimming
ensures optimum resistor stability. Diamond sawed
for dimensional uniformity and accuracy. Advanced
processing techniques, and Hi-Rel construction assure
optimum performance.
