Product Description

FSF-5050 470–475 MHz IF SAW Filters

Q: Which center frequencies are covered by the FSF-5050 470–475 MHz series?

This collection focuses on key UHF IF options around 470–475 MHz. Typical variants align to narrowband receiver IF plans. Contact FCom Fuji Crystal for exact part mapping and the latest confirmation sheets.

Q: What applications are best suited for these IF SAW filters?

Common uses include private radio networks, industrial telemetry/control terminals, narrowband wireless receivers and multi-stage UHF IF chains that require stable channel selectivity and strong out-of-band rejection.

Q: Do I need additional matching components?

The series targets 50Ω source/load conditions, so many designs can integrate directly. If your IF amplifiers or PCB environment present non-ideal impedance, small L/C trimming can help optimize flatness and insertion loss.

Q: How should I choose between nearby 470–475 MHz options?

Start from your IF frequency and required bandwidth, then prioritize stopband targets and temperature grade. Outdoor or higher-reliability terminals should choose wider temperature versions when available.

Q: Do you provide samples and engineering support?

Yes. We support sampling for evaluation, plus application engineering guidance for matching, fixture correlation and selection trade-offs. Contact us with your IF plan and bandwidth targets.

Key Features

The FSF-5050 470–475 MHz group is part of FCom Fuji Crystal’s IF SAW portfolio for UHF systems. It addresses the practical need for compact, mass-production-stable filters that can be integrated into multi-stage IF chains with minimal layout risk.

Compact 5×5mm land pattern for high-density IF layouts.
Typical low insertion loss with balanced passband flatness depending on the selected variant.
Multiple bandwidth/temperature grades to support commercial and industrial deployments.
50Ω source/load targets for simplified lab correlation and faster design convergence.

Typical Applications

Private radio and narrowband UHF terminals
Industrial telemetry, SCADA and wireless controllers
Multi-mode receivers requiring strong IF preselection
Special-purpose audio/data wireless links

If you need a tighter/ wider passband, custom stopband targets or adjacent IF frequencies beyond this range, FCom Fuji Crystal can evaluate customized SAW solutions.

Key Specs (Quick View)

Quick-view values are selection-oriented. Confirm final limits in the latest datasheet/confirmation sheet. Typical measurement context: 50Ω terminations, 25°C unless otherwise specified by the SKU.

Target Systems / Standards

Where this series is commonly used

UHF narrowband receivers and private radio networks
Industrial RF modules (telemetry/control), channelized architectures
Multi-stage IF chains where adjacent-channel suppression is the limiting case

Typical IF Placement

Receiver chain placement

LNA → Mixer → IF SAW filter → IF gain → ADC / demod
IF plan + channel bandwidth drive Fc/BW selection
Stopband offsets define adjacent-channel/blocker resilience

Electrical Orientation

What to align in reviews

Center frequency window: 470–475 MHz (by option)
Impedance: 50Ω source/load target
Insertion loss / ripple / group delay: variant-dependent

Matching / Impedance Notes

Integration checklist

Keep input/output traces short; preserve 50Ω continuity
Ground returns should be symmetrical to stabilize stopband behavior
If IF amp is not 50Ω, add small L/C trimming to reduce ripple

FSF-5050-474M	474 MHz	-	Enhanced adjacent-channel suppression	-40/-55 to +85°C	Suggested for outdoor/industrial receivers
FSF-5050-475M	475 MHz	Typically ~1.7–2.9 dB	Channel-specific IF windows	0 to +50°C / -40 to +85°C	Aligns with certain private network plans

Design Notes

50Ω Integration Tips

Maintain impedance continuity across the filter input/output to minimize passband ripple.
When paired with high-gain IF amplifiers, verify return loss and linearity to avoid unexpected compression.
Use short, symmetrical ground returns to keep out-of-band performance consistent across builds.

Reliability

Temperature & Production Consistency

Choose wider temperature grades for outdoor radios and industrial installations.
Validate stopband/IF spur scenarios during EVT/DVT with real RF shielding and enclosure constraints.
We can provide batch-level trend data to support your final acceptance criteria.

Applications

Why 470–475 MHz IF filtering matters

In narrowband UHF receivers, the IF chain often becomes the dominant limiter under real adjacent-channel and blocker conditions. A production-stable IF SAW filter helps enforce a predictable selectivity window before high IF gain and ADC stages, reducing desense and improving unit-to-unit correlation.

If your demodulation is sensitive to passband shape, consider ripple and group delay requirements early, then align your acceptance measurement method (fixture, reference plane, VNA settings).

Common deployment scenarios

Private radio networks: stable adjacent-channel rejection across production
Industrial wireless controllers: robust out-of-band suppression in dense RF environments
Multi-stage IF designs: repeatable gain distribution and spur control

Ordering Code / Options

How to specify

Frequency point: 470 / 472 / 474 / 475 MHz (or request adjacent points)
Bandwidth definition: share required passband edges (and dB definition if available)
Temperature grade: commercial vs industrial (e.g., 0 to +50°C, -40 to +85°C)
Interface: 50Ω termination assumption; note if IF stages are high impedance

For RFQ, include your IF plan, channel bandwidth, required attenuation offsets, and any group delay/ripple constraints.

FAQ

Which center frequencies are covered by the FSF-5050 470–475 MHz series?

This collection focuses on the most requested IF selections around 470–475 MHz for UHF narrowband designs. Exact part definitions may map to specific channel plans. Contact us for the latest confirmation sheets and recommended options for your receiver.

What applications are best suited for these IF SAW filters?

Typical uses include private radio networks, industrial telemetry terminals, narrowband data links and multi-stage UHF IF chains where stable selectivity and solid out-of-band rejection are required.

Do I need additional matching components?

Designed around 50Ω conditions, many systems can integrate directly. If your layout constraints or amplifier interfaces are non-ideal, small L/C tuning can help optimize passband flatness and insertion loss.

How should I choose between nearby 470–475 MHz options?

Choose the center frequency based on your IF plan, then compare the required bandwidth, ripple limits and temperature grade. Outdoor or higher-reliability terminals should prioritize wider temperature options.

Do you provide samples and engineering support?

Yes. We support sampling for evaluation and application engineering guidance (matching, fixture correlation, and selection trade-offs). Share your IF plan and bandwidth targets for a faster recommendation.

What about MOQ, lead time and pricing?

We provide quotations by inquiry (RFQ). MOQ and lead time depend on the exact SKU, temperature grade and validation requirements. Send your target part(s) or IF plan to receive an updated quote.

Can you customize bandwidth or stopband targets?

Yes. Custom SAW designs are available for specific bandwidth edges, stopband shaping, group delay control and integration constraints. Share your mask/offset targets and measurement setup for review.

Can you provide test reports or measurement guidance?

We can support acceptance-style measurement alignment (VNA setup, fixture definition, reference plane and parameter checklist). Ask for recommended test conditions and documentation options for your build stage.

Need a More Targeted UHF IF Solution?

FCom Fuji Crystal supports additional FSF-5050 IF frequency points and customized SAW designs focused on stopband shaping, group delay control and package-level integration.
