Procurement Notes

Verify the specific datasheet version from Anatech Electronics Inc. to confirm exact mechanical tolerances and electrical limits. Ensure compatibility with 50 Ohm system impedance. Check for RoHS compliance status if required by regulatory standards. Confirm package orientation and pinout definitions against the official drawing before integration.

Selection Notes

Select this component when a 40 MHz bandwidth at 2.5 GHz is required for LTE Band 7. Consider the 5.5 dB insertion loss impact on system gain. The 18-SMD package size must fit within the available PCB area. Verify that the return loss specification meets the transmitter/receiver protection requirements.

Part Context

This part belongs to the ceramic filter category from Anatech Electronics Inc. Ceramic filters are commonly used in RF applications due to their high Q-factor and stability. The AM2500B1377 specifically targets cellular bands, distinguishing it from general-purpose filters through its precise center frequency and bandwidth alignment with LTE standards.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Cross-referencing requires matching center frequency, bandwidth, impedance, and package dimensions exactly.
