WIFI4S2440-7

Overview

The WIFI4S2440-7 is a cavity bandpass RF filter manufactured by Anatech Electronics Inc., designed for the 2.4 GHz ISM band. It features a center frequency of 2440 MHz with a -1 dB bandwidth of 22 MHz, covering the passband from 2425 to 2455 MHz. The component exhibits an insertion loss of less than 2.0 dB and a ripple of 0.25 dB. It operates with a standard 50 Ohm input/output impedance and provides greater than 45 dB attenuation at 2490 MHz. The physical height is 27.00 mm.

Feature Summary

• Constructed as a rigid cavity bandpass filter for stable RF performance
• Optimized for the 2.4 GHz Wi-Fi frequency range
• Provides high out-of-band rejection exceeding 45 dB

Applications

• Military communication systems
• Defense radar and signal processing
• Commercial wireless infrastructure

Procurement Notes

Verify the specific revision suffix if required, though the base model indicates standard specifications. Confirm RoHS compliance status through official documentation before integration. Ensure mechanical clearance accommodates the 27.00 mm maximum height. Validate connector type compatibility with system interfaces. Request current datasheets to confirm manufacturing origin details.

Selection Notes

Select this component when precise filtering within the 2425-2455 MHz range is critical. The low insertion loss supports efficient signal transmission in sensitive RF chains. High attenuation at adjacent frequencies makes it suitable for environments requiring strict spectral purity. Consider the cavity construction for applications demanding long-term stability under varying thermal conditions.

Part Context

This part belongs to Anatech Electronics' line of cavity bandpass filters, which cover frequencies from 0.1 to 47 GHz. These components are engineered for high-power handling and exceptional selectivity. The series is widely utilized in professional and industrial sectors where reliability outweighs size constraints.

Replacement Considerations

No public substitute part numbers are confirmed for direct replacement. Cavity filters often require custom tuning; verify electrical overlap with potential alternatives carefully.
