AFS2442.0S4-T

Overview

The Abracon LLC AFS2442.0S4-T is a Surface Acoustic Wave (SAW) filter designed for Bluetooth applications. It operates at a center frequency of 2.442 GHz with a bandwidth of 78 MHz and an insertion loss of 1.9 dB. The component features a 50 Ohm impedance and supports a maximum DC voltage of 10 V. It is housed in a compact 6-SMD surface mount package measuring 3 mm x 3 mm x 1.4 mm. The device functions within an operating temperature range of -20°C to +70°C.

Feature Summary

• Low insertion loss for efficient signal transmission
• Excellent attenuation bandwidth characteristics
• Surface mount design for automated assembly

Applications

• Bluetooth technology modules
• RF signal conditioning circuits
• Wireless communication devices

Procurement Notes

Verify the specific datasheet version for precise electrical tolerances and thermal limits before integration. Confirm RoHS compliance status matches current regulatory requirements for your target market. Ensure the 6-SMD footprint aligns with your PCB layout constraints. Cross-reference the 10V DC rating against your circuit's power supply specifications to prevent overvoltage damage during operation.

Selection Notes

Select this component when designing Bluetooth RF front-ends requiring a 2.442 GHz center frequency. The 78 MHz bandwidth suits standard Bluetooth data rates. Consider the 1.9 dB insertion loss impact on overall system gain. The 50 Ohm impedance ensures compatibility with standard RF traces. Evaluate the -20°C to +70°C range against environmental conditions.

Part Context

This part belongs to Abracon's SAW filter series, specifically optimized for ISM band applications. It complements other filters in the AFS24xx series by providing targeted filtering for Bluetooth protocols. The SMD form factor allows for high-density board layouts common in modern portable electronics.

Replacement Considerations

Check for direct substitutes from Abracon or other manufacturers offering identical 2.442 GHz center frequencies and 6-SMD packages. Verify that alternative parts match the 78 MHz bandwidth and 1.9 dB insertion loss specifications to maintain signal integrity without redesigning the RF matching network.
