1. Introduction
The Taoglas DXP.02.A is a compact SAW diplexer for use in any navigation system
application using the GPS/GALILEO L1, L2 & L5 bands.
The diplexer is designed to function as both a bandpass filter for each band and to
either split one path into three or to combine the bands back into one RF feed. For
example, a customer who wanted to use passive antenna elements would need to
implement a diplexer in some cases to split the bands out into separate paths. It is also
designed to isolate and reject any unwanted GPS signals from getting to the
application port.
It is housed in a compact 5*5*1.7mm over-molded laminate package and is easy to
integrate using SMT process mounting directly onto the target PCB.
