112.32MHz SAW IF Filter

Preliminary Information

DS3811 - 3.4 October 11995

The DW9249 112.32MHz SAW I.F. filter has been

specifically developed for the Digital European Cordless

Telephone (DECT) market.

By using a centre frequency of 112.32MHz, the DW9249

overcomes the potential problems of 6th and 8th harmonic

interference often associated with filters centred at

110.592MHz.

The filter offers excellent temperature stability, (ST-Quartz

substrate) plus low Group Delay Ripple (±100ns max.) and is

available in the latest, low profile ceramic surface mount

package technology.

FEATURES

■ Extremely Low Group Delay Ripple

■ Wide Operating Temperature

■ High Co-channel rejection

■ High Adjacent Channel Rejection

■ Highly Reproduceable Impedance Characteristics

■ Balanced or Unbalanced Drive

■ Low Profile Leadless Ceramic Surface Mount Package

Suitable for Automated Assembly
