AM1555B988

Overview

The AM1555B988 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 1.555 GHz with a bandwidth of 30 MHz. The component features a 50 Ohm impedance and utilizes a monoblock package design with two PCB pads. Physical dimensions are 0.339 inches in length and 0.287 inches in width (8.60mm x 7.30mm). Insertion loss is specified as less than 2.5 dB, with rejection greater than 30 dB at 1626 MHz and within the 1515-1615 MHz range.

Feature Summary

• Monoblock ceramic construction for stable RF performance
• Designed for high-frequency bandpass filtering applications
• Surface mount compatible with standard PCB pad layouts

Applications

• RF front-end modules requiring 1.555 GHz signal selection
• Wireless communication systems operating in the 1.5 GHz band
• Test and measurement equipment filters

Procurement Notes

Verify the specific datasheet version from Anatech Electronics Inc. to confirm exact insertion loss and rejection values for your batch. Ensure PCB footprint matches the 8.60mm x 7.30mm monoblock package dimensions. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference pinout and pad configuration with official assembly drawings before integration.

Selection Notes

Select this component when a fixed 30 MHz bandwidth at 1.555 GHz is required. The monoblock style offers compactness compared to discrete LC solutions. Consider the 50 Ohm system impedance match for minimal reflection. Evaluate thermal stability requirements against ceramic material properties. Compare physical size constraints against available board space.

Part Context

This part belongs to the family of ceramic bandpass filters produced by Anatech Electronics Inc. These components are engineered for radio frequency applications where size and performance stability are critical. The monoblock technology integrates resonators into a single ceramic body, providing robust mechanical integrity and consistent electrical characteristics across temperature variations.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model. Direct replacement requires matching the 1.555 GHz center frequency, 30 MHz bandwidth, and 50 Ohm impedance. Verify that any alternative component fits the 8.60mm x 7.30mm footprint and maintains similar insertion loss specifications.
