The 856999 is a high-performance Surface Acoustic Wave
(SAW) duplexer designed to meet the strict CDMA
requirements for use in the Cellular extension band, also
known as Band Class 10 (BC10).
856999 is specifically designed to meet the high performance
expectations of insertion loss, isolation and triple beat for
CDMA systems over the extended bandwith of BC10
applications under all operating conditions. Due to the
exceptional Receive isolation and GPS rejection performance
no transmit SAW filter should be required.
