General Description
856979 is a high-performance Temperature Compensated
Surface Acoustic Wave (TC SAW) duplexer designed to
meet the strict LTE requirements for use in Band 20.
The 856979 is specifically designed to meet the high
performance expectations of insertion loss, isolation and
linearity in LTE systems operating in Band 20 applications
under all operating conditions. The use of TC SAW
technology enables stable performance over the entire
temperature range.
