1000th unit of SPDR resonator
On March 13, 2020, QWED celebrated its jubilee sale of the 1000th unit of dielectric-resonator-based test-fixture for microwave measurements of electromagnetic properties of materials. The "1000th RESONATOR by QWED" plaque was mounted on a 5GHz SPDR, based on the original designs of Professor Jerzy Krupka, a distinguished long-time collaborator of QWED.
