DW9268

240.192MHz IF SAW Filter

Advance Information

DS4025 - 1.4 October 1995

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.
