E7000

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. 

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. 

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.
