Overview: DW9268 DW9268 240.192MHz IF SAW Filter Advance Information
DS4025 - 1.4 October 1995 The DW9268 has been designed specifically for the Digital Cordless Personal munications 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 pliant to the DECT mon Interface specification Part 2 - The Physical Layer. The device also exhibits excellent closein and ultimate rejection, which bined with a Group Delay Ripple of 200ns maximum makes the DW9268 and ideal IF filter for Digital Cordless Personal munications systems. The device is packaged in a surface mount, leadless ceramic chip carrier, suited to high volume automated assembly systems.
