AB921B927

Overview

The AB921B927 is a cavity bandpass RF filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 921 MHz and supports a bandwidth range of 915-928 MHz. The component features a 13 MHz bandwidth specification and exhibits an insertion loss of 1.5 dB. It is constructed as a module equipped with SMA connectors for interfacing.

Feature Summary

• Cavity construction for stable RF filtering performance
• Bandpass configuration centered at 921 MHz
• Integrated SMA connector interface

Applications

• Radio frequency signal processing
• Communication system filtering
• RF module integration

Procurement Notes

Verify the specific suffix designation, such as -S, against official documentation to confirm connector type and exact electrical tolerances. Ensure the required operating frequency aligns with the 915-928 MHz range. Confirm RoHS compliance status through the manufacturer's current datasheet or statement before procurement.

Selection Notes

Select this component when a fixed center frequency of 921 MHz is required. The 13 MHz bandwidth suits applications needing narrowband rejection outside the passband. Verify that SMA connectors match the system interface requirements. Consider the cavity package size for mechanical integration constraints.

Part Context

Anatech Electronics Inc. specializes in standard and custom radio frequency filters for military and commercial sectors. The AB921B927 belongs to their cavity bandpass filter series, designed for reliable performance in RF environments requiring precise frequency selection and isolation.

Replacement Considerations

Cross-reference part numbers like AM921B1301 for potential alternatives within the same product family. Verify identical center frequency and bandwidth specifications before substitution. Connector compatibility must be confirmed.
