Quartz Substrates Used for Classroom Experiments
A university professor requested a quote for the following:
I am trying to design a classroom experiment for my students and I wanted to use products as part of the setup.
- How do I know the resonant frequency of the Single Crystal Quartz Wafer?
- What is the excursion per volt of the same should I induce a voltage into the same.
What I am trying to build is a resonant circuit that with a pickup antenna, tunable capacitor and a crystal. I would prefer to have a resonant circuit at either 64MHz or 128MHz as those are the narrow band transmitters that I have at my disposal. the circuit that I have in mind would be a pick-up coil antenna in parallel with a tunable capacitor and both in parallel with your crystal.

Finally do you have resources or suggestions where I could have a few of the same assembled?

Where are Quartz Substrates Used?
Single crystal quartz substrates are widely used in electronic and optoelectronic industries due to their excellent properties, such as high purity, high stability, low thermal expansion, and high mechanical strength. Here are some general specifications of single crystal quartz substrates that are commonly available:
- Diameter: 1 inch (25.4 mm), 2 inches (50.8 mm), 3 inches (76.2 mm), 4 inches (101.6 mm), 5 inches (127 mm), 6 inches (152.4 mm), 8 inches (203.2 mm), 12 inches (304.8 mm), and larger.
- Thickness: typically from 0.3 mm to 1.0 mm, but thicker substrates are also available.
- Orientation: typically (0001) or (11-20) for hexagonal quartz, or (100) for cubic quartz.
- Surface finish: polished or lapped, with roughness typically in the range of 1-10 nm.
- Dopants: optionally, some substrates may be doped with impurities to modify their properties, such as to create p-type or n-type conductivity.
However, it's important to note that the specific specifications of single crystal quartz substrates can vary greatly depending on the manufacturer and intended use. It's best to consult a supplier or manufacturer directly for detailed information about the specifications and availability of specific single crystal quartz substrates.
