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
