High Frequency
Surface Mount Attenuators
PAT-S Series
•
RoHS compliant
•
Frequency operation up to 10GHz
•
Low parasitic capacitance and inductance
•
Thin film stability over time and temperature
The PAT chip attenuator series is available in a wide range of power
ratings from 32mW to 250mW. The surface mount package is ideal for
applications where parasitic capacitance and inductance are concerns. Typical applications include wireless
communication receivers and transmitters.
