Overview
The SF1088A is a Surface Acoustic Wave (SAW) filter designed for signal conditioning applications. It operates at a nominal center frequency of 170.6 MHz with a passband range of 170.50 to 170.70 MHz. The device features an insertion loss of 8.0 dB and a bandwidth of 180 kHz. It supports a maximum voltage rating of 30 V and maintains a 50 Ohm impedance. The component utilizes a 10-SMD, No Lead package suitable for board mount installation.
Feature Summary
- Surface Acoustic Wave technology for precise RF signal filtering
- Optimized for GSM intermediate frequency applications
- Low insertion loss design for efficient signal transmission
Applications
- GSM communication systems
- Intermediate frequency filtering in RF receivers
- Signal conditioning modules
Procurement Notes
Verify the specific package variant and manufacturing date code against the latest official datasheet before procurement. Confirm that the 10-SMD, No Lead form factor matches your PCB footprint requirements. Ensure compatibility with the 170.6 MHz center frequency specification for your target GSM application. Check for any updated RoHS compliance documentation from the manufacturer.
Selection Notes
Select this component when a narrow 180 kHz bandwidth is required around 170.6 MHz. The 8.0 dB insertion loss is suitable for standard gain stages. Ensure the 30 V voltage rating exceeds your circuit's peak operating voltage. The SMD package requires appropriate reflow soldering profiles compatible with lead-free processes.
