Abstract
An RF connector comprising a coaxial transmission structure that transmits RF power at RF and microwave frequencies through a dielectric seal. Portions of the connector on either side of the seal do not make metal to metal contact. The connector has input and output connector portions having outer conductors coaxially disposed around inner conductors with dielectric material disposed therebetween. Impedance matching transition portions abut each side of the dielectric seal that have a relatively large diameter adjacent the dielectric seal that transitions to a relatively small diameter distal from the dielectric seal. Tapered and stepped impedance matching transition portions may be employed. A shunt capacitance is disposed approximately one quarter wavelength from each side of the dielectric seal in the stepped transition version. RF energy transmitted by way of the input connector portion is capacitively coupled through the dielectric seal to the output connector portion.
