Positioning & Design Highlights

The FSF-5050 460–465 MHz group is part of FCom Fuji Crystal’s UHF IF SAW portfolio, aimed at receivers requiring tight channel selectivity and reliable rejection of adjacent interferers. The 5×5mm footprint supports compact RF/IF layouts without sacrificing stable production performance.

Small 5.0×5.0 mm SMD package for high-density layouts.
50Ω source/load basis for easier system integration.
Multiple center-frequency options aligned with UHF IF plans.
Balanced insertion loss and out-of-band attenuation for narrowband receivers.

Target Systems / Typical Standards

Typical target systems include professional/LMR-style receivers, private radio networks, industrial telemetry and control radios. For design-in, validate blocker profile, adjacent-channel mask, and IF amplifier linearity targets at the board level.

Typical IF Placement

A common placement is directly after the mixer (first or second IF) as the primary bandpass element to suppress adjacent interferers before high-gain IF amplification.

Typical Applications

Professional radio and private network terminals
Industrial telemetry, control and data radios
Multi-stage UHF receiver IF selection
Narrowband wireless modules requiring robust interference control

If your architecture requires a different bandwidth target, customized rejection masks or adjacent center frequencies, FCom can evaluate tailored SAW solutions.

Matching / Impedance Notes

Designed around 50Ω source and load; keep transitions and vias controlled to minimize ripple.
Place close to the IF amplifier input; avoid long stubs that can create resonances near passband edges.
If return loss or group delay is critical, fine-tune with small L/C trimming based on VNA + on-board measurements.

Integration Tips

50Ω IF Chain Best Practices

Maintain impedance continuity in traces and transitions to minimize passband ripple.
Validate return-loss interaction with high-gain IF amplifiers.
Use short, symmetric routing around the filter footprint where possible.

Validation

Prototype-to-Mass-Production Handoff

Complete EVT/DVT verification of temperature drift and adjacent-channel rejection.
Request sample-lot measurement trends if your application is sensitive to ripple or group delay.
Finalize the exact spec grade prior to procurement release.

Ordering Code / Options

Use the FSF-5050 ordering code to lock down the center frequency and grade for your IF plan. If you have a blocker-driven rejection mask or a unique bandwidth target, FCom can evaluate a tailored option.

Ordering Guidance

Start with IF plan: choose 460 / 462 / 464 / 465 MHz center frequency.
Confirm bandwidth/ripple targets by receiver channel plan and adjacent interferers.
Select temperature grade to match environment and reliability requirements.
Request confirmation sheet for final limits and production release.

Selection Path / Upgrade Options

If you are shifting IF allocations or optimizing rejection, compare nearby collections and validate with your board-level IF chain: SAW Filters family, 470–475 MHz, 480 MHz, 499–499.25 MHz.

Most Common Options

Center frequency: 460 / 462 / 464 / 465 MHz
Impedance reference: 50Ω source/load
Package: FSF-5050, SMD 5.0×5.0 mm
Temperature grade: industrial or commercial variants

For customization: adjacent frequencies, rejection masks, or bandwidth tailoring can be reviewed by the applications team.

FAQ

Which center frequencies are covered in the FSF-5050 460–465 MHz collection?

This collection focuses on 460, 462, 464 and 465 MHz center-frequency variants in the 5×5mm FSF-5050 package. They are designed for 50Ω UHF IF chains and narrowband receiver architectures. Adjacent custom frequencies can be evaluated upon request.

What applications are these UHF IF SAW filters suited for?

Typical use cases include professional radio and private networks, industrial telemetry and control radios, multi-stage UHF receivers and other narrowband wireless front ends that require stable IF selectivity and strong out-of-band rejection.

Do I need an extra matching network?

The series is based on a 50Ω source/load design, so many systems can integrate it directly. If your PCB impedance environment or IF amplifier conditions are unique, minor L/C trimming based on board-level measurements may further optimize insertion loss and passband flatness.

How should I choose between 460, 462, 464 and 465 MHz options?

Select the center frequency according to your IF plan or channel allocation, then confirm bandwidth, ripple and temperature grade for your environment. FCom can provide sample data and confirmation sheets for final production release.

Can I request samples, lead time, or a quote without a listed price?

Yes. This is a B2B component page: pricing depends on frequency option, grade, quantity and logistics. Contact FCom for MOQ, lead time, sample requests, and customization evaluation.
