AM4425B1742

Overview

The AM4425B1742 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 4.425 GHz and provides a bandwidth of 250 MHz, covering the range from 4300 to 4550 MHz. The component features a 50 Ohm impedance and is housed in a 16-SMD module package. Maximum insertion loss within the bandwidth is specified at 3.0 dB. The device is lead-free and RoHS compliant, designed for RF and microwave applications requiring precise frequency selection.

Feature Summary

• Ceramic construction for stable RF performance
• Bandpass filtering capability centered at 4.425 GHz
• RoHS compliant and lead-free manufacturing

Applications

• RF signal processing systems
• Microwave communication equipment
• Frequency selective circuits

Procurement Notes

Verify the specific package variant when ordering, as connectorized versions such as AM4425B1742-C exist alongside surface mount modules. Confirm that the required impedance matches the standard 50 Ohm specification. Ensure compliance with RoHS standards if mandated by project requirements. Check availability status as active components may have varying supply chain conditions. Validate physical dimensions against PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when a fixed center frequency of 4.425 GHz is required for bandpass filtering. Consider the 250 MHz bandwidth to ensure it accommodates the desired signal spectrum without excessive attenuation. Evaluate the 16-SMD package type against available board space and mounting methods. Compare insertion loss specifications against system sensitivity requirements to ensure signal integrity is maintained throughout the transmission path.

Part Context

Anatech Electronics Inc. specializes in designing and manufacturing RF and microwave filters ranging from 100 kHz to 20 GHz. This company holds ISO 9001:2015 certification and focuses on high-performance filter solutions.
