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 specifically 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.
