General Description
The 856327 is a bandpass RF SAW filter specifically
designed for the North American, Unlicensed,
Industrial, Scientific and Medical band at 915 MHz
The filter BW covers the entire available band
from 902 to 928 MHz.
The filter’s low insertion loss, 50 ohm matched ports
and compact footprint simplify system integration.

All specifications are based on the test circuit on page 3
In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance
over temperature
Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing
tolerances

Typical values are given at 25 C
Relative to zero dB
This is the optimum impedance in order to achieve the performance shown
