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.
