General Description
The 854678 is an IF SAW filter with a center frequency
of 70 MHz and a minimum 3 dB bandwidth of 36 MHz.
It features excellent passband response, very good
rejection, and low group delay ripple. The small size of
this surface mounted filter makes it an economical
choice for demanding applications for high data rate
communications standards.

Notes:
1. All specifications are based on the TriQuint schematic for the main reference design shown on page 3
2. All specifications are tested at room temperature only
3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing
tolerances
4. Typical values are based on average measurements at room temperature
5. Relative to Insertion loss at center frequency
6. This is the optimum impedance in order to achieve the performance shown
