These 50-Ω matched bandpass microwave RF filters are designed for the worldwide standard wireless voice and data communications frequencies being used 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 16-year plus RF communications component manufacturing experience and very high volume manufacturing capability to meet customer demands. FEATURES • Low insertion loss • Small size, light weight • 50-Ω matched SAW Filter Summary [1] Part Number MBF9411B MBF9412B Pass Frequency (MHz) 824 to 849 869 to 894 Insertion Loss (dB) <3.5 <3.5 Stop Frequency (MHz) 869 to 1049 779 to 849 Attenuation (dB) >30 >30 • 6-pin SMD package • High reliability Description CDMA Transmit Filter CDMA Receive Filter 1.
