SF1059A

Overview

The SF1059A is a Surface Acoustic Wave (SAW) filter manufactured by Murata Electronics, designed for signal conditioning applications. It operates at a nominal center frequency of 350.0 MHz with an 800 kHz bandwidth and typical insertion loss of 8 dB. The component utilizes a surface mount package configuration without leads, suitable for automated assembly processes in compact electronic devices.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF signal filtering
• Engineered specifically for WLAN intermediate frequency processing
• Provides stable performance within defined passband characteristics

Applications

• WLAN intermediate frequency filtering
• RF signal conditioning modules
• Wireless communication device front-ends

Procurement Notes

Verify the exact package type against official datasheets prior to procurement. Confirm that the specific revision matches design requirements. Ensure compatibility with existing PCB footprints. Check for any recent lifecycle status updates from the manufacturer. Validate electrical parameters against current application specifications.

Selection Notes

Select this component when a 350 MHz SAW filter is required for WLAN IF stages. Consider the 800 kHz bandwidth relative to system channel spacing. Evaluate the 8 dB insertion loss impact on overall link budget. Assess the surface mount form factor against available board space constraints.

Part Context

This part belongs to Murata's SAW filter portfolio, which provides passive RF components for wireless communications. These filters are distinct from active amplifiers or digital processors, serving primarily as frequency-selective elements to isolate desired signals from noise and interference in receiver chains.
