AM851B1120

Overview

The AM851B1120 is a ceramic band pass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 851 MHz and provides a bandwidth of 38 MHz, covering the range from 832 to 870 MHz. The component features an insertion loss of 3.2 dB and is designed for a system impedance of 50 Ohms. It is housed in an 8-SMD module package with dimensions of 17x13 mm.

Feature Summary

• Utilizes ceramic technology for RF filtering applications
• Provides band pass functionality centered at 851 MHz
• Designed for 50 Ohm impedance systems

Applications

• RF signal processing circuits
• Microwave communication systems
• Band selection in receiver front-ends

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer specifications may be updated. Confirm that the 8-SMD package dimensions (17x13mm) match your PCB footprint requirements. Ensure compatibility with 50 Ohm system impedance before integration into the design.

Selection Notes

Select this component when a fixed center frequency of 851 MHz is required. The 38 MHz bandwidth defines the passband width. Consider the 3.2 dB insertion loss impact on signal strength. The SMD package size must fit the available board space.

Part Context

Anatech Electronics Inc. specializes in RF and microwave filters. This part belongs to their ceramic filter line, which typically offers compact solutions for specific frequency bands. The company focuses on design and manufacturing of such components for industrial and commercial use.

Replacement Considerations

Check for direct substitutes with identical 851 MHz center frequency and 38 MHz bandwidth. Verify pinout compatibility for the 8-SMD package. Ensure replacement parts maintain the 50 Ohm impedance and similar insertion loss characteristics.
