Dielectric Resonators

Exxelia offers TE Dielectric Resonators (DR) in a wide range of dielectric constants (from 24 to 78), in the form of disk and cylinder type, exhibiting exceptionally high "Q" factor and temperature stability, for applications ranging from 1.5 GHz to 100 GHz.

 

They are commonly utilized in oscillators, satellite communication systems (reception LNB’s), microwave filters and combiners, radio-communication, industrial (motion detection sensor), automotive (anticollision radar), across a wide frequency spectrum, up to 40 GHz. 

 

Dielectric standoffs and spacers are also available.

 

Resonators can be combined with frequency tuning screws on request.

Frequently Asked Questions

Find answers to the most frequently asked questions about our products and services.
What are the specifications of 4 mm wave tuning elements?

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. 

What are the specifications of the 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. 

What are the typical specifications of dielectric tuning elements?

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. 

What are the key specifications to consider for metallic tuning elements?

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.

What are the key specifications to consider when selecting resistive tuning elements?

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