Description

The DW9268 has been designed specifically for the Digital Cordless Personal Communications market as an IF filter with a centre frequency of 240.192MHz. The filter utilises GPS's low loss (7dB typical), Transversal filter technology based on a Quartz substrate for excellent temperature stability.

A 3dB passband of 1.3MHz (typical) is maintained whilst providing  rejection  to  adjacent  and  alternate  interferers compliant to the DECT Common Interface specification Part 2- The Physical Layer. The device also exhibits excellent close-in and ultimate rejection, which combined with a Group Delay Ripple of 200ns maximum makes the DW9268 and ideal IF filter for Digital Cordless Personal Communications systems.

The  DW9268 device  is  packaged  in  a  surface  mount,  leadless ceramic  chip  carrier,  suited  to  high  volume  automated assembly systems.
