Microwave Calipers
Microwave calipers are fixtures that mount two AMMP sensors on a “C”-shaped yoke so that it can be positioned to measure microwave transmission through a sheet or slab specimen. It is combined with a two-port vector network analyzer (VNA), which can be either integrated into the handle or placed nearby and connected with RF cables.
Applications of the Microwave Calipers:
- Microwave Calipers are used to measure transmission through single-layer or multi-layer specimens. Depending on which spot probes are used, it can operate from 2-18 GHz or 20-40 GHz. Examples of how these are used include:
- Verifying coatings on aircraft transparencies.
- Monitor the microwave transmission and/or intrinsic properties of materials during the manufacturing process, in such materials as quartz or fiberglass composite prepreg, resistive sheets, etc.
- Within manufacturing applications or repair depots.
- In conjunction with flat or semi-curved components and materials.
Benefits of the Microwave Calipers:
- Portable, free-space measurement system.
- Ability to measure the actual components or production materials in-situ, preventing the need for witness coupons that may or may not be representative of the actual production material.
Additional Information:
- Lightweight and adjustable fixture.
- Versatile and easy to use with multiple specimen types and sizes.
- Customized CTGcalc™ software to assist in the taking of RF measurements.
- Can be integrated with Compass Technology Group’s AMMP sensors (SP218, SP324, and SP2040).
- Can be combined with a tripod stand for easy manipulation around large components.
