WIFI2422-3O

Overview

The WIFI2422-3O is a cavity bandpass filter manufactured by Anatech Electronics Inc., designed for Wi-Fi applications. It operates at a center frequency of 2422 MHz with a bandwidth of 22 MHz, covering the passband from 2411 MHz to 2433 MHz. The component features a standard input and output impedance of 50 Ohms. Physically, it measures 108.00 mm in length and 56.00 mm in width.

Feature Summary

• Provides precise signal selection within the 2.4 GHz Wi-Fi spectrum
• Constructed as a robust cavity resonator for stable performance
• Engineered for high rejection of out-of-band interference

Applications

• Wi-Fi channel 3 filtering systems
• Wireless local area network (WLAN) infrastructure
• RF front-end modules requiring specific 2422 MHz isolation

Procurement Notes

Verify that the ordering suffix 'O' corresponds to the specific variant details provided in official documentation. Confirm physical dimensions and mounting requirements match the design constraints. Ensure the manufacturer is correctly identified as Anatech Electronics Inc. to avoid confusion with similar part numbers from other vendors.

Selection Notes

Select this component when a fixed center frequency of 2422 MHz is required for Wi-Fi channel 3 operations. The 22 MHz bandwidth suits standard 20 MHz channel widths with necessary guard bands. Consider the physical size of the cavity package during layout planning to ensure adequate clearance and mechanical stability.

Part Context

This part belongs to a series of cavity bandpass filters targeting the 2.4 GHz ISM band. Similar models like WIFI2417-2 and WIFI2427-4 cover adjacent channels. These components are typically used in environments where high selectivity and power handling are critical compared to planar filter technologies.

Replacement Considerations

Direct substitutes may include WIFI2422-3 if the 'O' suffix denotes only packaging or minor non-functional differences. Verify electrical specifications against the original datasheet before substitution.
