General Description
The 857031 is a high performance Surface Acoustic Wave
(SAW) Notch Filter designed to reject emissions in the BC0
band while passing Band 13 LTE band.
857031 is specifically designed to enable simultaneous voice
and LTE for Band 13 application. It is specified to support
Band 13 requirements in the entire 746 - 787 MHz band.
The 857031 uses advanced packaging techniques to achieve an
industry-leading 2.5 x 2.0 x 0.56 mm package. The filter
exhibits excellent power handling capabilities.

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. All power levels are referenced to the antenna port. Two CW tones are applied at frequencies f1 and f2, and the resultant intermodulation
product in the 746-756 MHz band is measured. The first tone (f1 = 785 to 787 MHz, 24 dBm referenced to the antenna port) is applied at the
input port. The second tone (f2 = 824 to 828 MHz, 13 dBm referenced to the antenna port) is applied at the output port. The intermodulation
product is measured at 746 to 750 MHz
