AB1650B518

Overview

The AB1650B518 is a cavity bandpass RF filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 1650 MHz with a minimum bandwidth of 20 MHz. The component features SMA connectors and exhibits a maximum insertion loss of 2.5 dB within the passband. Minimum return loss is specified at 15 dB. This module is designed for radio frequency applications requiring precise signal filtering.

Feature Summary

• Cavity construction for stable RF performance
• Bandpass filtering centered at 1650 MHz
• Integrated SMA connectors for direct interfacing

Applications

• Radio frequency signal processing
• Communication system filtering
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version for the AB1650B518 to confirm mechanical dimensions and environmental ratings. Ensure SMA connector compatibility with existing system interfaces. Cross-reference electrical specifications against current design requirements to validate insertion loss and return loss margins under operating conditions.

Selection Notes

Select this component when a fixed center frequency of 1650 MHz is required. Consider the 20 MHz bandwidth constraint for signal integrity. Evaluate the 2.5 dB insertion loss impact on system gain. Verify that the cavity package size fits the available chassis space compared to planar alternatives.
