AM2250B558

Overview

The AM2250B558 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 2250 MHz and features a bandwidth of 100 MHz, covering the range from 2200 to 2300 MHz. The component exhibits an insertion loss of less than 2.0 dB. It provides attenuation greater than 18 dB at 2100 MHz and greater than 14 dB at other specified out-of-band frequencies. The device is housed in an 8-SMD package and is designed for 50 Ohm systems.

Feature Summary

• Utilizes ceramic technology for stable bandpass filtering performance
• Designed for 50 Ohm impedance matching in RF circuits
• Provides high attenuation outside the passband to suppress interference

Applications

• RF front-end modules requiring 2.25 GHz signal selection
• Wireless communication systems operating within the 2200-2300 MHz range
• Test and measurement equipment needing precise bandpass characteristics

Procurement Notes

Verify the specific datasheet version for the AM2250B558 to confirm exact electrical tolerances and mechanical dimensions before integration. Ensure that the 8-SMD package footprint matches the PCB layout requirements. Confirm that the supplier provides official documentation from Anatech Electronics Inc. to guarantee component authenticity and performance consistency in critical RF applications.

Selection Notes

Select this component when a fixed 100 MHz bandwidth at 2250 MHz is required with low insertion loss. Consider the 8-SMD form factor for surface-mount assembly constraints. Evaluate the attenuation specifications at 2100 MHz against system noise floor requirements. Compare against similar Anatech models like the AM2260B1039 if different center frequencies or bandwidths are needed for the specific application design.

Part Context

This part belongs to the series of ceramic bandpass filters produced by Anatech Electronics Inc. These components are engineered for radio frequency applications where compact size and reliable filtering are essential. The AM2250B558 specifically targets the 2.25 GHz spectrum, offering a solution for signals within the 2200-2300 MHz range while rejecting adjacent channel interference through its defined stopband characteristics.

Replacement Considerations

The AM2260B1039 is a related model from Anatech Electronics Inc. with a 2260 MHz center frequency and 40 MHz bandwidth. Verify compatibility if shifting frequency targets. No direct cross-manufacturer substitutes are confirmed in public data without detailed parameter matching.
