General Description
P
The 857271 is a high-performance IF SAW
bv
filter with a
center frequency of 456 MHz and a 1.4 dB bandwidth of
39.6 MHz.
It features low loss with
and is
designed to be used with a balanced input and output.
The small size of this surface mounted filter makes it an
economical choice for demanding applications such as
WCDMA/LTE or other similar high data rate
communications standards.
This device is RoHS compliant and Pb-free.

Notes:
1. All specifications are based on the test circuit shown on page 3.
2. In production, devices will be tested at room temperature to a guard-banded specification to ensure electrical compliance over
temperature.
3. Electrical margin has been built into the design to account for the variations due to manufacturing tolerances.
4. Variation is defined as the total peak to peak variation over the defined frequency range.
5. Measurement made with a RRC filtered QPSK modulated signal.
6. Measurement made only during engineering development.
7. Measurement made relative to insertion loss at Center Frequency, F
0.
