General Description
856931 is a high-performance Surface Acoustic Wave
duplexer designed to meet the strict LTE requirements for
use in Band 17.
The 856931 is specifically designed to meet the high
performance expectations of insertion loss, isolation and
linearity in LTE systems operating in Band 17 applications
under all operating conditions.
The 856931 uses common module packaging techniques to
achieve the industry standard 2.5 x 2.0 mm
2
footprint. The
duplexer exhibits excellent power handling capabilities.
