AM1090B1023

Overview

The AM1090B1023 is a ceramic band pass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 1090 MHz and features a 50 Ohm impedance. The component utilizes a 7-SMD module package with dimensions of 12x10mm. Key electrical specifications include a bandwidth of 10 MHz, insertion loss of less than 4 dB, and stopband attenuation exceeding 30 dB at +/- 35 MHz offset frequencies.

Feature Summary

• Utilizes ceramic resonator technology for stable band pass filtering characteristics
• Designed for surface mount integration via a compact SMD module configuration
• Provides high selectivity with defined stopband rejection capabilities

Applications

• RF front-end filtering in communication systems operating near 1.09 GHz
• Signal conditioning in wireless infrastructure equipment
• Interference suppression in receiver input stages

Procurement Notes

Verify the specific datasheet version from Anatech Electronics Inc. to confirm mechanical tolerances and thermal ratings. Ensure compatibility with standard SMD reflow profiles. Cross-reference pinout diagrams against PCB layout requirements to prevent installation errors during assembly processes.

Selection Notes

Select this component when a fixed center frequency of 1090 MHz is required with minimal insertion loss. Consider the 7-SMD footprint constraints and 50 Ohm system impedance matching. Evaluate the stopband attenuation requirements against potential interference sources in the target RF environment before finalizing the design.

Part Context

This part belongs to the Anatech Electronics Inc. ceramic filter series, which offers various center frequencies and bandwidths. These components are engineered for applications requiring reliable frequency selection without active power supplies. The series supports diverse RF design needs through standardized packaging options.

Replacement Considerations

Direct substitutes require identical 1090 MHz center frequency, 10 MHz bandwidth, and 7-SMD package dimensions. Verify that alternative ceramic filters maintain comparable insertion loss and stopband attenuation specifications to ensure circuit performance continuity.
