Patent No. 7,804,385 - Composite Resonator for use in Tunable or Fixed Filters
September 21, 2010
We are pleased to announce that RS Microwave has been issued US Patent 7,804,385: "Composite Resonator for use in Tunable or Fixed Filters". This important patent covers the use of hard and soft dielectric materials to construct stable bandstop or bandpass filters. See our Technical Corner Articles dated September 2008 and August 2010.
Patent No. 6,924,718 - Coupling probe having an adjustable tuning conductor
Received US Patent 6,924,718 in late 2005 covering Tunable Coupling Probes having an adjustable tuning conductor. British Patent number GB 2,410,622 granted April 2006. This development means that the coupling value between resonators in both bandpass and bandstop filters can be adjusted to ensure compliance with specification requirements, without having to disassemble the unit being adjusted. The result is time savings, cost reduction, and improved performance. The technique also is patented under the IPO in many countries of the world.
Patent No. 6,674,346 - Evanescent Resonators
Previously, US Patent 6,674,346 covering suspended evanescent resonators. The use of these resonators should result in a new generation of smaller, high performance bandpass and bandstop filters for high power communication systems. The new and very flexible technique was developed in conjunction with ongoing and shared research activities, at both RS Microwave and the New Jersey Institute of Technology. The new filters were developed at RS Microwave.
