General Description
885008 is a high-performance Bulk Acoustic Wave
(BAW) notch filter designed to reject emissions in the
WiFi bands, while passing both the 2.3 GHz & 2.6 GHz
WiMAX/LTE/TD-LTE bands.
885008 is specifically designed to enable coexistence of
WiFi and 4 G signals within the same device or in close
proximity to one another. The part is specified to
provide
Low loss in the entire USA WiMAX band (2496-2690
MHz) as well as LTE Bands 7 & 38. The filter also
passes the 2.3 GHz band: WiBro, WCS, Band 40 & the
Indian 4 G band.
885008 uses inexpensive packaging techniques to
achieve an industry-leading 1.7 x 1.3 x .46 mm package.
The filter exhibits excellent power handling capabilities.
885008 is referenced on multiple designs with the
leading WiMAX chipset makers.

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. Typical values are based on average measurements at room temperature, unless otherwise noted
4. Relative to zero dB
5. This is the optimum impedance in order to achieve the performance shown.
