FSF-5050-480M 480MHz IF SAW Filter for UHF IF | FCom Fuji Crystal
8-SMD, 5.0x5.0
FEATURE
Product Description
FSF-5050-480M 480 MHz IF SAW Filter
A compact 5.0×5.0 mm SMD IF SAW filter centered at 480 MHz for UHF receiver architectures. Designed around 50Ω environments to deliver low insertion loss, stable passband behavior and dependable out-of-band suppression in volume production.
Key Features
The FSF-5050-480M belongs to FCom Fuji Crystal’s FSF-5050 UHF IF SAW portfolio. It targets 480 MHz IF channel selection in compact receiver chains where board space, selectivity and consistent mass-production performance are equally important.
- Miniaturized 5×5 mm SMD footprint for high-density RF/IF layouts.
- 50Ω interface design for easier integration and characterization.
- Optimized for low insertion loss and stable passband ripple behavior.
- Suitable for industrial and private-radio-grade reliability targets.
Target Systems & Typical IF Placement
- Target systems: private mobile radio, industrial wireless modules, compact multi-stage UHF receivers.
- Typical IF placement: mixer output → IF SAW filter → IF amplifier/limiter → demod/ADC. A stable 50Ω environment helps preserve passband flatness.
Applications
- Private mobile radio and specialized UHF terminals
- Industrial telemetry, control and data radio modules
- Compact multi-stage UHF receivers
- Dedicated narrowband or moderate-band IF architectures
Why These Specs Matter (Practical View)
- 480 MHz center frequency: aligns with UHF IF channel plans used to balance selectivity and implementation cost.
- 50Ω interface: reduces matching complexity and improves fixture-to-board correlation during EVT/DVT.
- 5×5 mm footprint: supports dense receiver layouts while retaining robust assembly behavior.
If your design requires adjacent center frequencies, specific passband targets, or tailored out-of-band rejection profiles, we can evaluate additional FSF-5050 IF options and customization.
Key Specs
Test-condition note (design guidance): typical references are based on 50Ω source/load and fixture-level measurement near 25°C; verify final performance with your board layout and impedance transitions.

Detailed Specifications
The following values are a practical selection guide for early-stage design. Final production specs should follow the latest FCom confirmation documents.
| Parameter | Typical Range | Notes |
|---|---|---|
| Center Frequency (Fc) | 480 MHz | UHF IF channel selection |
| Package | 5.0×5.0 mm SMD | Optimized for compact RF modules |
| System Impedance | 50Ω | Designed for standard IF/RF environments |
| Insertion Loss | Low-dB class (application dependent) | Verify with board-level layout and matching |
| Out-of-Band Rejection | High attenuation class | Supports robust co-channel and adjacent-channel performance |
| Compliance | RoHS / Lead Free | Standard FCom environmental control |
50Ω Board-Level Best Practices
- Keep impedance continuity across pads and launch transitions.
- Minimize via stubs and avoid sharp bends near the filter.
- Validate passband ripple with S-parameter measurements in EVT/DVT.
Samples, Volume, and Manufacturing Consistency
- Sample support for bring-up and pilot builds.
- Volume supply for production programs with stable performance control.
- Request extended temperature screening if your terminal is outdoor-rated.
Ordering Code / Options
Ordering code: FSF-5050-480M. For receiver projects, options are typically evaluated against your IF plan (center frequency, passband and rejection targets) and your operating environment.
Common Option Dimensions
- Center frequency: adjacent IF frequency planning within FSF-5050 portfolio
- Bandwidth shaping: narrow-to-moderate passband targets per channel plan
- Temperature grade: request screening aligned to indoor/outdoor terminal rating
- Packaging: SMD production packaging suitable for automated assembly
Selection Path / Upgrade Options
Use nearby-frequency pages to shortlist candidates, then confirm final bandwidth/rejection targets via RFQ.
