The DW9268 is an IF filter with a centre frequency of 240.192MHz, designed specifically for the Digital Cordless Personal Communications market. It uses 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 an 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.
The Mitel DW9268 is an Intermediate Frequency (IF) Surface Acoustic Wave (SAW) filter specifically designed for the Digital Cordless Personal Communications market.
