Microwave Tuning Elements

Tuning Elements consist of a brass mounting bushing with a rotor of the same material including a tuning rod made of metallic or dielectric or absorbent material and a nut.  

Metallic Tuning Elements consist of a brass mounting bushing with an integral tuning rotor of the same material and a nut. Bushing is gold plated, rotor and nut are passivated. Optional materials and plating are available upon request. 

The millimeter Wave Tuning Elements are higher frequency versions of both Tuning Elements described in this data sheet.  Part number: AT 6922 ROHS. Bushing and rotor are made of brass gold plated. Usage in the frequency bands X to K. Bushing can be mounted with solder, epoxy or press-fit. 

Dielectric Tuning Elements are used whenever the lowest loss tuning for high frequency applications is required. When dielectric rod is introduced into a cavity, the self resonant frequency is lowered due to the cavity “appearing” larger. 

 The basic dielectrics used in Exxelia Ceramics Microwave Tuning Elements are sapphire, quartz and alumina. 

Metallic Tuning Elements consist of a brass mounting bushing with an integral tuning rotor of the same material and a nut. Bushing is gold plated, rotor and nut are passivated.  Optional materials and plating are available upon request.

Resistive Tuning Elements provide a consistent and accurate means of attenuating microwave energy. Rod made of magnetically loaded epoxy exhibits broadband lossy properties. 

Exxelia is certified EN 9100, a quality standard specific to the aerospace, space, and defense sectors. Our facilities are also ISO 9001 certified (quality management), and some are certified ISO 13485 for medical devices. Other industry-specific standards, such as NADCAP or AQAP, may also apply depending on the products and markets.

The EN 9100 standard ensures a rigorous quality management system tailored to the critical requirements of the aerospace, space, and defense industries. It is required by major OEMs such as Airbus, Safran, Thales, or CNES. This certification guarantees product traceability, risk management, and compliance with international standards.

Yes, some of our facilities are ISO 13485 certified, the quality standard for medical devices. This certification enables Exxelia to design and manufacture components (such as coils, sensors, or capacitors) used in high-reliability medical equipment, including MRI scanners, ventilators, and imaging systems.

The railway industry demands durability, reliability, and long service life. While a dedicated certification like EN 9100 is not required, Exxelia applies IRIS standards and complies with IEC/EN regulations specific to railway applications. Our quality processes ensure component compliance for trains, metros, and tramways, including fire safety and electromagnetic compatibility.

Yes. Exxelia meets defense industry requirements through its EN 9100 certification and compliance with military standards (MIL-STD, STANAG). Our components are qualified for critical applications such as RF systems, embedded electronics, guided munitions, or radar systems. Some products are also subject to customer-specific qualification procedures.
