DW9268
240.192MHz IF SAW Filter
Advance Information
Replaces October 1995 version, DS4025-1.4
DS4025-2.0 January 2000
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 device is packaged in a surface mount, leadless
ceramic chip carrier, suited to high volume automated
assembly systems.
