THICK FILM
ATTENUATORS, DIGITAL
DROP-IN REMOVABLE SMA GENERAL INFORMATION
The DAD Series of Precision Digital Attenuators utilize Thick Film Technology for all microwave and logic functions. All conductors, attenuator elements and bias resistors are screened on a single alumina substrate to achieve increased reliability and enhanced performance. All additional circuit elements including pin diodes, integrated circuits, capacitors, and coils are bonded directly to the Thick Film. Customized driver circuits are integrated on the RF substrate.
