Abstract
A shorting stub for connection between an inner conductor and an outer conductor of a coaxial cable. The shorting stub of a tungsten or tungsten alloy, having a connecting portion between an inner conductor connection and an outer conductor connection. The shorting stub may be cost effectively formed using metal injection molding techniques. The connecting portion may be formed by a plurality of loop segments in a range of different configurations. If needed, one or more supports may be applied to support the shorting stub during the metal injection molding.
Claims15
A shorting stub for connection between an inner conductor and an outer conductor of a coaxial cable, comprising:
- a tungsten or tungsten alloy shorting stub having a connecting portion between an inner conductor connection and an outer conductor connection;
- the connecting portion provided with at least two loop segments;
- each of the loop segments arranged in a separate, parallel plane;
- each of the separate planes aligned parallel to one another and normal to a longitudinal axis of the inner conductor;
- each of the loop segments interconnected with at least one other loop segment by a transition section.
A method for manufacturing a shorting stub for connection between an inner conductor and an outer conductor of a coaxial cable, comprising the steps of:
- forming a tungsten or tungsten alloy shorting stub by metal injection molding;
- the shorting stub provided with a connecting portion between an inner conductor connection and an outer conductor connection;
- the connecting portion provided with at least two loop segments;
- each of the loop segments arranged in a separate, parallel plane;
- each of the separate planes aligned parallel to one another and normal to a longitudinal axis of the inner conductor;
- each of the loop segments interconnected with at least one other loop segment by a transition section;
- and
- sintering the shorting stub.
A method for manufacturing a shorting stub for connection between an inner conductor and an outer conductor of a coaxial cable, comprising the steps of:
- forming a green part tungsten or tungsten alloy shorting stub by metal injection molding;
- the green part tungsten or tungsten alloy shorting stub having a connecting portion between an inner conductor connection and an outer conductor connection;
- the connecting portion having multiple loop segments, each of the loop segments arranged in a separate, parallel plane;
- each of the separate planes aligned parallel to one another and normal to a longitudinal axis of the inner conductor;
- each of the loop segments interconnected with at least one other loop segment by a transition section;
- the loop segments supported during the metal injection molding by at least one support;
- debinding and sintering the green part tungsten or tungsten alloy shorting stub;
- and
- removing the at least one support.
