AM2250B1283

Overview

The AM2250B1283 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 2250 MHz with a bandwidth of 100 MHz, covering the range from 2200 to 2300 MHz. The component features an insertion loss of less than 2.0 dB and maintains a 50-ohm impedance. It is housed in an 8-SMD module package measuring 13x12 mm. The filter provides significant attenuation outside the passband, exceeding 28 dB at 1638-1880 MHz, over 45 dB at 3800-4800 MHz, and more than 15 dB from DC to 1900 MHz.

Feature Summary

• Utilizes ceramic construction for stable RF performance
• Designed as a bandpass filter with specific center frequency tuning
• Integrated into an 8-SMD surface-mount module format

Applications

• Aerospace radio frequency systems
• Commercial microwave communication equipment
• Military RF filtering applications

Procurement Notes

Verify the exact datasheet version and RoHS status before procurement. Confirm that the 8-SMD module dimensions match your PCB layout requirements. Ensure compatibility with the 50-ohm system impedance. Check for any specific handling instructions regarding the ceramic material. Validate that the supplier is authorized to provide genuine Anatech Electronics components.

Selection Notes

Select this component when a fixed 2250 MHz center frequency is required. Consider the 100 MHz bandwidth for signal isolation needs. Evaluate the insertion loss specification against system sensitivity limits. Assess the physical size constraints of the 13x12 mm module. Verify that the ceramic technology meets environmental stability requirements for the intended application.
