General Description
The 856879 is a high-
performance Temperature
Compensated Surface Acoustic Wave (TC SAW)
duplexer designed to meet the strict LTE requirements
for use in Band 13.
856879 is specificall
y designed to meet the high
performance expectations of insertion loss, isolation
and BC14 rejection in LTE systems operating in B13
applications under all operating condition. The use of
TC SAW technology guarantees these specifications
up to the extended +90C operating condition.
The 856879 uses common packaging techniques to
achieve the industry standard 2.5 x 2.0 mm footprint.
The duplexer exhibits excellent power handling
capabilities.
Temperature Compensated SAW; DC blocking
capacitor required.
