SF0640BA03206S
SAW Filter
640 MHz SAW Filter, 100 kHz Bandwidth
• 5 x 5 mm Ceramic LCC, 8 Pads
• RoHS Compliant
These filters are manufactured on quartz, which provides optimal temperature performance and are available from 80
-1600 MHz. This TCRF is designed for narrowband IF filtering such as in satellite transponders, directional finders and
anti-jam modems. Other packaging styles are available for more rugged environments and applications. Standard part
numbers as well as custom solutions are available. Please contact sales for more information.
