AM784B1257

Overview

The AM784B1257 is a ceramic band pass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 784.5 MHz and provides a bandwidth of 8.5 MHz, covering the range from 780.25 MHz to 788.75 MHz. The component features an insertion loss of less than 3.0 dB and is designed for a 50 Ohm impedance system. It is housed in an 8-SMD module package.

Feature Summary

• Utilizes ceramic technology for stable band pass filtering performance
• Designed for 50 Ohm impedance applications
• Provides low insertion loss characteristics

Applications

• RF signal processing circuits
• Communication systems requiring specific frequency selection
• Electronic equipment utilizing ceramic filters

Procurement Notes

Verify the exact center frequency of 784.5 MHz and bandwidth of 8.5 MHz against design requirements. Confirm the 8-SMD package dimensions and pin configuration match the PCB layout. Ensure the 50 Ohm impedance rating aligns with the system interface. Check for any specific mounting or handling instructions provided in the official datasheet.

Selection Notes

Select this component when a narrow band pass filter centered at 784.5 MHz is required. The 8.5 MHz bandwidth suits applications needing precise frequency isolation within the VHF range. Consider the 8-SMD form factor for surface mount assembly constraints. Evaluate the <3.0 dB insertion loss against system sensitivity requirements.

Part Context

This part belongs to the Anatech Electronics Inc. ceramic filter series. Similar models like AM784B1276 offer different bandwidths such as 17 MHz. These components are typically used in RF front-ends where size and stability are critical. The product line focuses on fixed-frequency filtering solutions for electronic devices.

Replacement Considerations

Cross-reference with other Anatech ceramic filters if bandwidth adjustments are needed. Verify compatibility with existing PCB footprints before substituting. Ensure replacement parts maintain the 50 Ohm impedance and similar insertion loss specifications.
