一、Characteristics
Te01delta-mode dielectric resonators (also known as TE01delta-mode ceramic resonators) are mechanical resonators made of highly stable ceramic materials with pressure effects by firing. When a voltage is applied, it deforms due to the piezoelectric effect and resonates at a specific frequency, the resonance frequency of which is determined by its vibration mode and the length and thickness of the ceramic substrate. The shortcoming of the TE01δ mode dielectric resonator is that its frequency accuracy is poor, usually, the frequency accuracy of the quartz crystal is 0.001%, but in the mode ceramic resonator it reaches 0.5%, so the mode ceramic resonator is limited to the circuit with low precision requirements.
TE01δ mode dielectric resonator has a wide range of dielectric constant (covering 6-130), high Q value, low temperature, used in microwave circuits such as oscillators in wireless communication, usually with filters, multiplexers, and other communication signals, which is used to form the miniaturization of microwave circuits and the basic device for the composition of high performance products.

三、Application & attention
Because ceramic resonators are cheaper than quartz crystals, they are often used instead of quartz crystal units as reference clocks or signal sources for electronic circuits, but because ceramic resonators are thermally stable, It is also widely used in aviation and sea, radar T/R components, electronic countermeasures, remote sensing, telemetry, Doppler induction, satellite communications, aerospace, radar, electronic countermeasures and other national defense and military fields.
Ceramic resonator products are highly customized products with flexible design. Because the indicators of microwave components are related to each other and sound to each other, the user needs to clearly state the indicator requirements before customization. Once the product is made, it cannot be changed. If there are indicators that exceed the physical limit of the material itself, the best indicators can be achieved through negotiation between the two parties. The company customized TE01δ mode dielectric resonator, TE01δ mode ceramic resonator.
