TRIMMER CAPACITORS

Gigahertz trimmers

GIGAHERTZ TRIMMER CAPACITORS

Description

•

Gigahertz trimmers

are tiny trimmer capacitors which provide a straight-forward technique for ﬁne

tuning RF and microwave circuits by eliminating time consuming methods of abrasive trimming, cut

and try adjustment techniques, and inter-change of ﬁxed capacitors.

• The design involved the need from a virtually indestructible miniature trimmer with superior electrical

characteristics.

• Gigahertz trimmers whistand the rigors of soldering heat, excessive tuning and rough handling. As a

result of the excellent dielectric and insulation properties of the sapphire housing, high breakdown

voltage is achieved. Incorporating the self-locking constant torque drive mechanism which eliminates

the need for external bushing slots, the new Gigahertz trimmers offer many improvements: a ﬁxed

length, increased Q, essentially zero tuning noise and reduced susceptibility to solder ﬂux intrusion

during installation.

• A variety of mounting styles is available for vertical, printed circuit, panel, cavity and strip-line

applications.

• Gigahertz trimmers can be delivered with permanent sealing cap which resists intrusion of solder ﬂux

and cleaning agents and allows easy access to the tuning rotor.
