DW9276

71MHz IF SAW Filter

Replaces January 2000 version, DS4087-3.0

DS4087-3.1 July 2002

DESCRIPTION

The DW9276 is a 71MHz IF SAW filter which has been

specifically designed for cellular radio architectures using

the highly integrated ‘Sceptre’™ hardware platform for

GSM from AT&T Microelectronics.

OUTPUT

Based on quartz for excellent temperature stability, the

DW9276 provides very high channel selectivity, low

Group Delay Ripple and Insertion Loss. Packaged in a

Surface Mount, low profile leadless chip carrier, the

DW9276 is ideally suited to high volume automatic

assembly systems.
