AM1090B1448

Overview

The AM1090B1448 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 1.09 GHz and provides a bandwidth of 6 MHz. The component features a 50 Ohm impedance and an insertion loss of 3.5 dB. Its passband spans from 1087 MHz to 1093 MHz. Attenuation specifications include greater than 60 dB at frequencies between 1129 MHz and 1400 MHz, greater than 37 dB at 1030 MHz, and greater than 15 dB at other specified out-of-band frequencies.

Feature Summary

• Ceramic construction for stable RF filtering
• Bandpass configuration centered at 1.09 GHz
• 50 Ohm system impedance compatibility

Applications

• RF signal processing in communication systems
• Frequency selection in receiver front-ends
• Interference rejection in wireless infrastructure

Procurement Notes

Verify the specific datasheet version for precise attenuation curves and mechanical dimensions before integration. Confirm that the 50 Ohm impedance matches your system requirements. Ensure the operating temperature range aligns with your environmental conditions. Check for RoHS compliance status if required by your manufacturing standards. Validate pinout or terminal configurations against your PCB layout.

Selection Notes

Select this component when a narrow 6 MHz bandwidth is required around 1.09 GHz. The low insertion loss of 3.5 dB makes it suitable for sensitive RF chains. Consider the ceramic package size for space-constrained designs. Evaluate the steepness of the skirt selectivity provided by the >60 dB attenuation specs for adjacent channel rejection needs.

Part Context

Anatech Electronics Inc. specializes in high-performance microwave and RF components. The AM1090B1448 belongs to their line of ceramic filters designed for reliable performance in demanding RF environments. These components are typically used in applications requiring precise frequency control and minimal signal degradation within specific bands.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the exact 1.09 GHz center frequency, 6 MHz bandwidth, and 50 Ohm impedance characteristics. Verify mechanical footprint compatibility if considering alternative manufacturers.
