MBF93xx
Surface Acoustic Wave (SAW) Filters
DESCRIPTION
The new MBF93xx Surface Acoustic Wave (SAW) filters utilize OKI’s third generation design and manufacturing technology to achieve a high out of band attenuation, low insertion loss, and low manufacturing cost in an industry standard 6-pin package 1.6 mm thick and 3.8 mm square.
These 50 Ω matched bandpass microwave RF filters are designed for the worldwide standard wireless
voice and data communications frequencies being utilized by cellular and wireless local-loop service providers. They have achieved design acceptance by leading wireless handset manufacturers in North
America, Europe, and Asia.
OKI’s lowest insertion loss SAW filters and high performance GaAs devices are used to reduce transmitter complexity. Receiver designs can be simplified by using the higher Tx frequency attenuation SAW
filters.
These devices take advantage of OKI’s over 15 year RF communications component manufacturing experience and very high volume manufacturing capability to meet true customer demands.
FEATURES
• Low insertion loss
• Small size, light weight
•50Ω matched
