General Description
The 856496 is a high-performance IF SAW filter with a
center frequency of 208 MHz and a 1 dB bandwidth of 3.84
MHz.
It features low loss with excellent attenuation, and is
designed to be used with a balanced pin input and output.
The small size of this surface mounted filter makes it an
economical choice for demanding applications such as
WCDMA or other similar high data rate communications
standards.
This device is RoHS compliant and Pb-free.

Notes:
1. All specifications are based on the TriQuint schematic for the main reference design shown on page 3
2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
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 minimum insertion loss
6. This is the optimum impedance in order to achieve the performance shown
