AM748B1188

Overview

The AM748B1188 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 748 MHz and an 8 MHz bandwidth. The component features a 50 Ohm impedance and utilizes an 8-SMD module package measuring 17x13 mm. Electrical specifications include a maximum passband insertion loss of 2.0 dB and a maximum ripple of 0.7 dB. Rejection performance is specified at a minimum of 25 dB within the 565.2-581.2 MHz range.

Feature Summary

• Utilizes ceramic construction for stable bandpass filtering characteristics
• Designed for surface-mount integration via SMD package
• Provides specific rejection capabilities in defined stopband frequencies

Applications

• U.S. military communication systems
• Microwave signal processing circuits
• RF front-end filtering applications

Procurement Notes

Verify the exact package dimensions and pin configuration against the official datasheet before integration. Confirm that the 50 Ohm impedance matches your system requirements. Ensure the operating temperature range aligns with your environmental conditions. Check for RoHS compliance status if required by your manufacturing standards. Validate the supplier's authorization to guarantee component authenticity.

Selection Notes

Select this component when a fixed 748 MHz center frequency with narrow 8 MHz bandwidth is required. Consider the physical size constraints of the 17x13 mm SMD footprint during PCB layout. Evaluate the insertion loss and ripple specifications against your link budget requirements. Ensure the stopband rejection meets interference mitigation needs in the 565-581 MHz range.
