WIFI2422-3

Overview

The WIFI2422-3 is a cavity bandpass filter manufactured by Anatech Electronics Inc., designed for WiFi applications. It operates at a center frequency of 2422 MHz with a bandwidth of 22 MHz, covering a passband from 2411 to 2433 MHz. The component features an input/output impedance of 50 Ohms and exhibits an insertion loss of 1.2 dB. Physically, it measures 4.252 inches in length and 2.205 inches in width (108.00 mm x 56.00 mm). The device is RoHS compliant.

Feature Summary

• Cavity construction provides high selectivity and stability for RF filtering
• Optimized for specific WiFi frequency bands with defined passband characteristics
• RoHS compliant manufacturing process

Applications

• WiFi signal filtering systems
• RF front-end modules requiring cavity bandpass performance
• Communication equipment operating within the specified 2411-2433 MHz range

Procurement Notes

Verify the manufacturer designation carefully, as sources list both Anatech Microwave Company and Anatech Electronics Inc. Confirm that the physical dimensions match your enclosure requirements, specifically the 108.00 mm x 56.00 mm footprint. Ensure the 50 Ohm impedance aligns with your system design. Check for RoHS compliance documentation if required for your regulatory standards.

Selection Notes

Select this component when a cavity filter topology is required for the 2422 MHz center frequency. The 22 MHz bandwidth suits applications needing precise filtering within the 2411-2433 MHz range. Consider the physical size constraints due to the larger cavity package compared to surface-mount alternatives. Verify insertion loss specifications against system link budget requirements.

Part Context

This part belongs to the category of RF cavity bandpass filters. Cavity filters are typically used in applications demanding high power handling and steep skirt selectivity. The specific model targets the 2.4 GHz ISM band region, commonly associated with WiFi communications. It serves as a passive component for signal conditioning in RF chains.
