Resonators play a vital role in electronic components, serving applications such as filters, oscillators, and amplifiers. They offer stable, resonant frequencies and excellent anti-interference performance. Common resonators include ceramic resonators, surface acoustic waves (SAW), crystals, and ceramics.
Understanding the performance specifications of resonators is crucial. These include oscillation frequency, frequency tolerance, total frequency stability, and operating temperature. By considering these specifications, designers can make informed choices to ensure precise frequency control and reliable performance in electronic systems that rely on resonators.
Coaxial resonators are widely used in electronic components, particularly in the design of voltage-controlled oscillators (VCOs), coaxial-resonator oscillators (CROs), and filters. These resonators comprise a ceramic coaxial line featuring an outer conductor with a square cross-section and a cylindrical center conductor. Coaxial resonators can be categorized into quarter-wavelength (λ/4) and half-wavelength (λ/2) forms, depending on the configuration of their ends.
One of the advantages of coaxial resonators is their ability to reduce the size of components due to their high dielectric constant (εr) values, which typically range from 10 to 100. Companies such as Integrated Microwave Corp., Trans-Tech, Tusonix, and Temex Ceramics offer a range of ceramic coaxial resonators in various sizes and εr values. These resonators find applications in oscillators, filters, bandpass/bandstop filters, electromagnetic interference (EMI) filtering, and telecommunications, covering frequencies from 200 MHz to 10 GHz. With their compact size and versatile applications, coaxial resonators provide an essential solution for achieving precise frequency control and efficient performance in electronic systems.
Ceramic resonators are an alternative to quartz crystals in electronic components, offering cost-effective and compact solutions. They utilize the mechanical resonance of piezoelectric ceramics, such as lead zirconium titanate (PZT), to generate oscillation at a specific frequency. Ceramic resonators can be used in oscillator configurations similar to quartz crystals. While they have lower accuracy and frequency stability than crystals, their advantages include smaller size, lower cost, and faster start-up time.
Murata’s CERALOCK Series ceramic resonators find applications in automotive electronics, communications, computing, and medical equipment. Other suppliers like Oscilent and Abracon offer ceramic resonators as well. Ceramic resonators are suitable for embedded systems with less stringent timing requirements, such as TV remote controls and toys. However, they may not replace quartz resonators in precision-driven applications like instrumentation and communication devices that demand higher accuracy and temperature stability.
With their affordability, compactness, and tolerance for shock and vibration, ceramic resonators provide an effective solution for various electronic applications, meeting the needs of cost-conscious designs without compromising functionality.

Dielectric resonators are versatile electronic components in applications such as filters, oscillators, and communication systems. They consist of a disc-shaped material with a high dielectric constant (εr), allowing for compact circuit designs. The confined electromagnetic fields within the dielectric resonator result in minimal radiation losses and a high-quality factor (Q). The TE01δ mode is commonly used, and coupling methods like microstrip lines enable the creation of components like dielectric-resonator oscillators (DROs).
Dielectric resonators serve as resonators for radio waves in the microwave and millimeter wave bands, with applications in electronic oscillators and bandpass filters. They utilize the unique properties of dielectric materials to create standing waves and control the frequency of generated radio waves. By leveraging their high dielectric constant and low dissipation factor, dielectric resonators provide reliable performance in various electronic systems.
Quartz crystal resonators are widely used as high-quality frequency-control elements in electronic components. Their piezoelectric properties allow them to convert mechanical energy into electrical energy, making them ideal for crystal oscillators. Quartz crystals offer advantages such as high-quality factor (Q) and superior frequency stability, making them preferred over LC oscillators. A thin slice of quartz is placed between two electrodes, and the resonator’s physical and electrical parameters are determined by the angle at which the quartz is cut. Quartz crystal resonators can be represented by an equivalent electrical circuit, whose impedance changes rapidly near the resonant frequency.
Quartz crystal resonators find applications in communication satellites, mobile devices, automotive electronics, TVs, personal computing, and home information appliances. The stability of their frequency characteristics, even with temperature changes, makes them reliable for precise timing requirements. With signal level variability and various voltage options, quartz crystal resonators can be used in multiple chips with different clock signal voltage requirements. Their accuracy ranges from 1PPM to 100PPM, providing reliable and stable frequency control for electronic systems.

Surface Acoustic Wave (SAW) resonators utilize acoustic waves propagating on a piezoelectric crystal surface to carry information. These resonators consist of interdigital transducers and grating reflectors that form a resonant cavity. They are widely used in electronic components such as oscillators, bandpass filters, and sensors for various physical factors. SAW resonators offer high stability, compact design, low power consumption, and robust performance in challenging conditions.
Notable characteristics of SAW resonators include their small size, low power requirements, wide operating temperature range, high-quality factor, high resonant frequency, high spectral purity, and reliability. They are ideal for applications requiring precise frequency control and are commonly used in wireless communication systems for filtering, frequency selection, and modulation. Companies like ECS Inc. International provide a range of SAW resonators for wireless security and remote control applications.
SAW resonators are vital in modern electronic systems, providing exceptional performance and integration capabilities. Their use extends to RF filters, timing circuits, frequency synthesis, and sensing applications—order resonators now through Tormeka.

Yttrium iron garnet (YIG) resonators find applications in the design of oscillators and filters in electronic components. These crystals possess a high-quality factor (Q), producing low-phase noise oscillators. Additionally, YIG resonators offer the advantage of achieving multi-octave bandwidths.
Typically configured in a spherical shape, YIG resonators rely on a direct-current (DC) magnetic field to resonate at microwave frequencies. The resonance is directly proportional to the strength of the applied magnetic field, which can be generated using an electromagnet, permanent magnet, or a combination of both.
YIG is a rare-earth garnet that finds widespread use in microwave devices, including radars, attenuators, filters, circulators, isolators, phase shifters, power limiters, and switches. It is also employed in microwave-integrated circuits where thin films are deposited on garnet substrates.
Using YIG resonators enables the development of high-performance microwave systems with excellent frequency stability, making them valuable components in various electronic applications. Buy resonators from Tormeka and get the best price and good customer service from our experts.
