FI212P085909-T

RF Multiplexers Overview

The FI212P085909-T is an RF diplexer manufactured by Taiyo Yuden, designed for surface-mount installation in a compact 0805 (2012 Metric) package. It operates across two distinct frequency bands: a low band ranging from 698 MHz to 960 MHz and a high band spanning 1.558 GHz to 1.61 GHz. The component provides signal isolation with a minimum attenuation of 25.00 dB in the low band and 19.00 dB in the high band. It maintains a standard impedance of 50 Ohms and functions within a temperature range of -30°C to +85°C.

RF Multiplexers Feature Summary

• Provides dual-band signal separation for LTE and GPS applications
• Compact 0805 surface-mount form factor suitable for space-constrained designs
• Ensures signal integrity through specified attenuation levels in both frequency bands

RF Multiplexers Applications

• LTE mobile communication devices
• GPS navigation systems
• W-CDMA and GSM handsets
• IS900 frequency applications

RF Multiplexers Procurement Notes

Verify the complete part number including the trailing suffix when sourcing components to ensure correct packaging configuration. Confirm that the specific revision matches the required frequency specifications for the target application. Cross-reference the manufacturer's official documentation to validate current lifecycle status and availability constraints before finalizing procurement plans.

RF Multiplexers Selection Notes

Select this component for designs requiring simultaneous operation in cellular and GNSS bands within limited board space. Ensure the circuit layout accommodates the 0805 footprint dimensions. Verify that the system impedance aligns with the 50 Ohm specification to minimize reflection losses. Consider the operating temperature range limits when evaluating environmental exposure conditions for the end product.

RF Multiplexers Part Context

This device belongs to Taiyo Yuden's SAW diplexer portfolio, which supports various wireless standards. It addresses the need for efficient signal routing in modern mobile terminals where multiple radio interfaces share antenna resources. The component enables compact integration of diverse communication protocols without significant interference between adjacent frequency bands.

RF Multiplexers Replacement Considerations

Consult official substitution lists for compatible diplexers with matching frequency ranges and package types. Verify electrical parameter equivalence before implementing any alternative part numbers to maintain system performance integrity.
