General Description
The 857182 is a high-performance Surface Acoustic
Wave (SAW) duplexer designed to meet the strict LTE
requirements for use in Band 17.
857182 is specifically designed to meet the high
performance expectations of insertion loss, isolation
and rejection in LTE systems operating in B17
applications under all operating condition.
The 857182 uses common packaging techniques to
achieve the industry standard 2.5 x 2.0 mm footprint.
The duplexer exhibits excellent power handling
capabilities.

All specifications are based on the TriQuint schematic for the main reference design shown on page 4
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 based on average measurements at room temperature
Relative to zero dB
This is the optimum impedance in order to achieve the performance shown
