• Optimized for specific wireless transmitter and receiver frequency bands

Applications

• Wireless transmitters
• Wireless receivers
• RF signal conditioning circuits

Procurement Notes

Verify the specific datasheet version when sourcing, as some distributor listings cite a 47.5 MHz bandwidth while official specifications indicate 95 MHz. Confirm the center frequency tolerance matches the target application requirements. Ensure the surface mount footprint aligns with the PCB layout constraints. Check RoHS compliance status if required by the manufacturing environment. Validate the operating temperature range against the intended deployment conditions.

Selection Notes

Select this component when a fixed center frequency of 1.567 GHz is required for dielectric filtering. The 95 MHz bandwidth suits applications needing moderate selectivity without excessive size. Consider the 50 Ohm impedance match for standard RF systems. The surface mount package facilitates high-volume production. Evaluate the thermal performance limits for environments exceeding standard room temperature operations.
