General Description
857005 is specifically designed for steep rolloff to
provide rejection in the FCC restricted bands
above and below the WiFi passband.
This
provides designers of access points the capability
to increase output power and improve range.
857005 uses advanced and inexpensive
packaging techniques to achieve an extremely
small 1.40 x 1.20 x 0.46 mm hermetically sealed
package.

Notes:
3. All specifications are based on the TriQuint schematic for the main reference design shown on page 3
4. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical
compliance over temperature
5. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing
tolerances
6. Typical values are based on average measurements at room temperature
7. Relative to zero dB.
8. This is the optimum impedance in order to achieve the performance shown
