AM1842B1659

Overview

The AM1842B1659 is a ceramic band pass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 1.8425 GHz with a bandwidth of 75 MHz. The component features a 50 Ohm impedance and is housed in a 20-pin SMD module package measuring 42x17 mm.

Feature Summary

• Ceramic construction for stable RF performance
• Band pass filtering characteristic
• Surface mount design

Applications

• RF signal processing
• Microwave communication systems
• Filtering applications requiring 1.8425 GHz center frequency

Procurement Notes

Verify the specific suffix (e.g., -E) against official datasheets to confirm mechanical dimensions and compliance status, as variations exist within the product line. Ensure the required impedance and bandwidth specifications match the system requirements before procurement. Confirm package type compatibility with PCB layout constraints.

Selection Notes

Select this component when a fixed center frequency of 1.8425 GHz and 75 MHz bandwidth are required. The 50 Ohm impedance must align with the surrounding circuitry. Consider the SMD-20P package size for board space limitations. Verify thermal and environmental ratings if operating in extreme conditions.

Part Context

Anatech Electronics Inc. specializes in RF and microwave filters. This part belongs to their ceramic filter series, designed for high-frequency applications. The company focuses on custom and standard filter solutions for telecommunications and industrial markets.

Replacement Considerations

Check for direct substitutes from Anatech or other manufacturers offering identical 1.8425 GHz center frequency, 75 MHz bandwidth, and 50 Ohm impedance in a compatible SMD package. Verify pinout and electrical characteristics match exactly.
