AM937B1322

Overview

The AM937B1322 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 937.5 MHz and features a passband range of 915-960 MHz. The component has a 45 MHz bandwidth and is designed for 50 Ohm impedance systems. Key electrical specifications include a maximum passband insertion loss of 3.0 dB and a maximum passband ripple of 1.0 dB. It provides a minimum rejection of 30 dB at 895 MHz. The device is housed in a 20-SMD module package.

Feature Summary

• Utilizes ceramic technology for stable RF filtering performance
• Designed for specific 915-960 MHz passband applications
• Provides defined rejection characteristics at off-frequency points

Applications

• RF signal processing in communication systems
• Microwave circuit filtering
• Military and commercial radio frequency equipment

Procurement Notes

Verify the exact package type and pin configuration against the official datasheet before integration. Confirm RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides traceable documentation matching the Anatech Electronics Inc. part number to avoid counterfeit components. Check for any specific handling requirements associated with ceramic filters.

Selection Notes

Select this component when a fixed 937.5 MHz center frequency with a 45 MHz bandwidth is required. Consider the 3.0 dB maximum insertion loss when designing for low-loss signal paths. The 50 Ohm impedance matches standard RF system architectures. Evaluate the 20-SMD module size against available PCB real estate constraints.

Part Context

Anatech Electronics Inc. specializes in the design and manufacturing of standard and custom RF and microwave filters. Founded in 1990, the company holds ISO 9001:2015 certification and serves both military and commercial markets. This ceramic filter represents their standard product line for specific frequency band applications.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the 937.5 MHz center frequency, 45 MHz bandwidth, 50 Ohm impedance, and 20-SMD package dimensions exactly.
