AM922B1591

Overview

The AM922B1591 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 922 MHz and features a bandwidth of 10.5 MHz, covering the range from 917.5 MHz to 928 MHz. The component has a nominal impedance of 50 Ohms and utilizes a 22-SMD module package. Key electrical specifications include an insertion loss of less than 3.6 dB. Attenuation characteristics specify greater than 20 dB rejection at 912.5 MHz.

Feature Summary

• Utilizes ceramic technology for stable RF filtering performance
• Designed as a bandpass filter with specific center frequency selection
• Constructed in a surface-mountable SMD module format

Applications

• RF signal processing systems requiring 922 MHz bandpass filtering
• Wireless communication infrastructure components
• Microwave circuit applications

Procurement Notes

Verify the exact datasheet specifications against your system requirements before procurement. Confirm that the 22-SMD package dimensions are compatible with your PCB layout. Ensure the 50 Ohm impedance matches your transmission line design. Check the insertion loss and attenuation values to guarantee signal integrity within your operational bandwidth constraints.

Selection Notes

Select this component when a fixed 922 MHz center frequency is required. The 10.5 MHz bandwidth defines the passband width. Consider the 22-SMD package size for space-constrained designs. Verify that the ceramic construction meets environmental stability needs. Compare attenuation specs at out-of-band frequencies like 912.5 MHz against system interference requirements.
