The SPDR (Split Post Dielectric Resonator) is your "Gold Standard" for sheet material testing. While the other resonators are great for wide-band sweeps, the SPDR is the industry favorite for extreme precision at specific frequencies.
Here is the rephrased version, optimized for a high-end technical website:
SPDR – Split Post Dielectric Resonator
The Industry Benchmark for High-Q Precision Dielectric Analysis
The WaveRay® SPDR series utilizes ultra-high-Q ceramic disk resonators to provide the most accurate complex permittivity measurements available for sheet materials. By isolating the ceramic discs from the metal shielding using low-loss dielectric supports, the SPDR achieves an intense, concentrated electromagnetic field—delivering unmatched sensitivity and data integrity.
Why Choose the SPDR?
- Elite Precision with High Q-Factors: With Q-factors exceeding 10,000, our SPDRs provide ultra-stable resonance for the highest possible accuracy in Dk/Df extraction.
- Nondestructive & Direct: Measure your samples in their native state without damage. Our proprietary software performs full permittivity extraction—no cumbersome lookup tables required.
- Specialized Specimen Stability: We provide customized tension strips for flexible materials, ensuring a perfectly flat Device Under Test (DUT) surface for flawless measurement consistency.
- Global Standard Compliance: Fully compliant with IEC 61189-2-721 and IPC-TM-650 2.5.5.15, making it the primary choice for certified material benchmarking.
- Tailored Engineering: Beyond our standard 1 GHz to 20 GHz range, we offer customized frequency builds and bespoke software interface designs to match your lab's specific workflow.
