📡 1、 Product Overview and Application Background

The device is called Microwave Dielectrometer, developed specifically for electrical design of wireless and high-speed digital devices. It is aimed at engineers and material developers, aiming to enable anyone to easily achieve high-precision dielectric constant measurement. The system provides multiple measurement methods for different measurement objects and frequency requirements.

📊 2、 Comparison of Three Main Measurement Modes

AET provides three core measurement modes, each targeting different forms of materials:

1. Hollow resonator TM mode (special for thin films/plates)

• Applicable subjectsPCB substrate, film, resin, glass, and ceramics, etc.

• characteristicBased on JIS C2565 standard, using the electric field variation of the central axis of the cylindrical cavity, it is suitable for measuring the tan δ of low dielectric loss materials such as PTFE or high-purity ceramics.

• parameterFrequency: 1GHz~10GHz, Dk range 1-30, Df range 0.1-0.0001, accuracy Dk ± 1%.

• Sample RequirementsSlender strip (width 3mm, thickness 0.05-1mm, length>80mm).

• 
  

2. Hollow resonator TE mode (5G high-frequency dedicated)

• Applicable subjects5G communication materials, high-speed signal transmission flexible circuit boards.

• characteristicSpecially designed for thin films with a thickness of less than 0.3mm, the frequency can reach 40GHz, and the fixed gap design ensures measurement stability.

• parameterFrequency: 10GHz~40GHz, Dk range 1-5, Df range 0.01~0.0001.

• standardCompliant with JIS R1641 and IPC-TM650 2.5.5.13.

• 
  

3. Coaxial resonator (non-destructive measurement)

• Applicable subjectsFinished components such as phone cases, connector molds, etc.

• characteristicNon destructive measurement using evanescent waves (near-field) at the opening without the need for sample processing.

• parameterA single resonator can measure 5 frequency points (covering 0.8GHz to 18.4GHz), with a Dk range of 1-15.

• Technical BackgroundDeveloped in collaboration with the Maeda Research Laboratory at the University of Tokyo, under the special license number 3691812.

🛠️ 3、 Measurement plan for special materials

• Powder/LiquidFill the sample with a quartz tube and determine the dielectric constant by calculating the filling rate based on true density; It can also be used for precise measurement of low polarity solvents.

• Cable materialSpecialized resonator design allows for high-precision measurement of wire insulation materials such as foamed PTFE.

• Ultra low loss ceramicsUsing a dielectric resonator, ceramic cylinders sandwiched between conductor plates resonate, suitable for materials with Df below 0.001.
