SPECIFICATION Part No. : DXP.01.A Product Name : SMD L1/L2 SAW Diplexer For GPS/GALILEO L1, GLONASS L2 & BeiDou B2 Features : L2 1222.7625 / L1 1575.42MHz SAW Diplexer SMT Direct Mount Compact Size 5*5*1.7mm Low Insertion Loss In band High Isolation Port to Port RoHS Compliant SPE-17-8-006/A/AW Page 1 of 11 1. Introduction The Taoglas DXP.01.A is an advanced compact SAW diplexer for use in any navigation system application using the GPS/GALILEO L1, GLONASS L2 and BeiDou B2 bands. The diplexer is designed to function as both a bandpass filter for each band and to either split one path into two or to combine both bands back into one RF feed. For example, a customer who wanted to use passive dual band antenna elements would need to implement a diplexer in some cases to split both bands out into separate paths. It is also designed to isolate and reject any unwanted GPS/GALILEO 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.
