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
