AM749B1190

Overview

The AM749B1190 is a ceramic band pass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 749 MHz and provides a minimum bandwidth of 9 MHz, covering a range from 744.5 to 753.5 MHz. The component features an input/output impedance of 50 Ohms and maintains a Voltage Standing Wave Ratio (VSWR) of 1.5:1. Signal insertion attenuation is specified at 2 dB. It is housed in an 8-SMD module package measuring 17x13 mm.

Feature Summary

• Ceramic construction for stable RF filtering performance
• Band pass signal filtering design optimized for specific frequency ranges
• Surface mount device (SMD) configuration for automated assembly

Applications

• RF front-end filtering in communication systems
• Signal conditioning in wireless transceivers
• Frequency selection in test and measurement equipment

Procurement Notes

Verify the exact datasheet version (AM749B1190.pdf) against your schematic requirements. Confirm that the 8-SMD package dimensions (17x13mm) fit your PCB layout constraints. Ensure the 50 Ohm impedance matches your system interface. Check RoHS compliance status if required by your manufacturing standards. Validate insertion loss specifications against your link budget calculations before finalizing procurement.

Selection Notes

Select this component when a fixed 749 MHz center frequency with 9 MHz bandwidth is required. The 50 Ohm impedance rating suits standard RF transmission lines. Consider the SMD-8 package size for space-constrained designs. Compare insertion loss and VSWR values against alternative filters to ensure signal integrity meets system specifications. Verify compatibility with operating temperature ranges defined in the official datasheet.
