AM1090S923

Overview

The AM1090S923 is a Surface Acoustic Wave (SAW) bandpass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 1.09 GHz with a bandwidth of 12 MHz. The component features an insertion loss of 0.9 dB and provides attenuation levels ranging from 36 dB to 50 dB depending on the specific test conditions. It is housed in an 8-SMD, No Lead package with dimensions of 0.150 inches by 0.150 inches (3.80 mm x 3.80 mm) and a maximum height of 0.055 inches (1.40 mm). The device supports an operating temperature range of 0°C to +85°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF filtering at 1.09 GHz
• Designed for surface mount installation in compact electronic assemblies
• Provides high selectivity with a 12 MHz bandwidth and significant out-of-band attenuation

Applications

• RF front-end filtering in wireless communication systems
• Signal conditioning in cellular infrastructure equipment
• Frequency selection in mobile handset transceivers

Procurement Notes

Verify the exact datasheet version from Anatech Electronics Inc. to confirm current manufacturing status and RoHS compliance. Ensure the 8-SMD no-lead package footprint matches the PCB design constraints. Confirm that the specified insertion loss and attenuation values meet the system requirements for the intended 1.09 GHz application environment.

Selection Notes

Select this component when a narrow 12 MHz bandwidth is required around the 1.09 GHz center frequency. Consider the low 0.9 dB insertion loss for signal integrity preservation. Evaluate the thermal stability within the 0°C to +85°C range against the operational environment. Compare the physical dimensions against available board space for the 8-SMD package.

Part Context

This part belongs to the Anatech Electronics SAW filter series, which includes various models for different frequency bands such as the AM110 series for lower frequencies. These components are engineered for consistent performance in RF applications requiring stable center frequencies and defined bandwidths. The AM1090S923 specifically targets higher frequency operations compared to other entries in the manufacturer's catalog.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with any alternative SAW filters based on identical center frequency, bandwidth, and package dimensions before implementation.
