SAW Filter Selection Guide

Find FCom SAW filters by series, package and center frequency. Compare bandwidth, insertion loss and stopband attenuation for IF, GNSS, ISM, Sub-GHz and RF front-end signal paths.

Not sure where to start?

Three ways to match your needs, or quickly contact FCom’s engineering team.

By Package Size & Mounting

Start with the available PCB area and assembly method, from miniature CSP platforms to standard SMD and through-hole packages.

Miniature CSP

Standard SMD

Through-Hole

By Frequency Band & Filter Requirement

Define the target center frequency or passband first, then narrow the choice by bandwidth, insertion loss and required rejection.

GNSS Bands

ISM/ Sub-GHz

IF/ VHF/ UHF

Low Insertion Loss

High Rejection

By Application

Use the signal-chain position and end equipment to establish the required band, blocker conditions, environmental limits and package platform.

Smart Metering

Remote Control

GNSS Receivers

Industrial Wireless

Automotive Telematics

Matched a series? Here’s what comes next.

Once you’ve narrowed down the series, the next step is confirming that the selected filter works in the actual signal chain—not only on the datasheet. FCom supports the following design-in process:

Phase 01 // Data

Request Technical Data

Access the latest product-specific datasheet, frequency-response data, package drawing, recommended land pattern and reflow profile. S-parameter files are available for selected parts.

Phase 02 // Engineering

Validate Filter Match

Submit the center frequency or passband, bandwidth, insertion-loss budget, rejection mask, source and load impedance, package and operating conditions. Our engineering team reviews matching, layout and board-level validation requirements.
