SF0122BA03286S
SAW Filter
121.5 MHz SAW Bandpass Filter, 25 kHz Bandwidth
• 7 x 5 mm Ceramic LCC, 10 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.
