What is SAW Resonator: Top Manufacturers for RF applications

A SAW resonator is a frequency-selective device that employs Surface Acoustic Wave technology to generate stable resonance characteristics in RF circuits. These resonators are commonly used in oscillators, frequency control systems, wireless communication modules, automotive electronics, and industrial applications requiring precise frequency references.

A SAW (Surface Acoustic Wave) device that oscillates at a specific radio frequency based on its design is known as an RF SAW resonator.

SAW Resonator Selection Guide

When choosing a SAW resonator, consider these technical specifications:

• Operating Center Frequency: The frequency at which the resonator is designed to operate.
• Configuration (1 port or 2 port): The number of ports the resonator has.
• Package Type: The physical packaging of the resonator (e.g., QCC12B, TO39, SIP4M, DCC6).
• Loaded Q: A measure of the resonator’s quality factor when loaded in a circuit.
• Untuned Insertion Loss (dB): The signal loss through the resonator when it is not tuned.
• Material Used: The piezoelectric material used in the resonator’s construction (e.g., Quartz, 36YX Quartz, 37YX Quartz).
