AC Coupled Pitch Adapters
AC Coupled Pitch Adapters (AC Fan-ins) provide a reliable interface for connecting DC-coupled silicon strip detectors to the standard ALIBAVA Daughter Board. The integrated AC coupling capacitors and bias polysilicon resistors simplify detector characterization while maintaining excellent signal integrity.
How It Works
The AC Coupled Pitch Adapter enables DC-coupled silicon strip detectors to operate with the standard ALIBAVA Daughter Board. Integrated AC coupling capacitors isolate the detector signal, while bias polysilicon resistors provide stable detector biasing, ensuring reliable electrical performance during detector characterization.
