Hermetic Aluminum Radio Frequency Interconnection And Method For Making
US Patent:
6037539, Mar 14, 2000
Filed:
Mar 20, 1998
Appl. No.:
9/045235
Inventors:
Riley D. Kilgo - Albuquerque NM
Larry Kovacic - Albuquerque NM
Richard K. Brow - Rolla MO
Larry Kovacic - Albuquerque NM
Richard K. Brow - Rolla MO
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
H01J 500
US Classification:
174 5061
Abstract:
The present invention provides a light-weight, hermetic coaxial radio-frequency (RF) interconnection having an electrically conductive outer housing made of aluminum or an aluminum alloy, a central electrical conductor made of ferrous or non-ferrous material, and a cylinder of dielectric material comprising a low-melting-temperature, high-thermal-expansion aluminophosphate glass composition for hermetically sealing between the aluminum-alloy outer housing and the ferrous or non-ferrous center conductor. The entire RF interconnection assembly is made permanently hermetic by thermally fusing the center conductor, glass, and housing concurrently by bringing the glass to the melt point by way of exposure to an atmospheric temperature sufficient to melt the glass, less than 540. degree. C. , but that does not melt the center conductor or the outer aluminum or aluminum alloy housing. The composition of the glass used is controlled to provide a suitable low dielectric constant so that an appropriate electrical characteristic impedance, for example 50 ohms, can be achieved for an electrical interconnection that performs well at high radio frequencies and also provides an interconnection maintaining a relatively small physical size.
High Thermal Expansion Sealing Glass For Use In Radio Frequency Applications
US Patent:
5965469, Oct 12, 1999
Filed:
Mar 20, 1998
Appl. No.:
9/045493
Inventors:
Riley D. Kilgo - Albuquerque NM
Richard K. Brow - Rolla MO
Larry Kovacic - Albuquerque NM
Richard K. Brow - Rolla MO
Larry Kovacic - Albuquerque NM
Assignee:
Sandia Corporation - Albuquerque NM
International Classification:
C03C 808
C03C 317
C03C 319
C03C 317
C03C 319
US Classification:
501 48
Abstract:
The present invention provides a glass composition for hermetically sealing to high thermal expansion materials such as aluminum alloys, stainless steels, and copper alloys, which includes between about 10 and about 25 mole percent Na. sub. 2 O, between about 10 and about 25 mole percent K. sub. 2 O, between about 4 and about 15 mole percent Al. sub. 2 O. sub. 3, between about 35 and about 50 mole percent P. sub. 2 O. sub. 5, B. sub. 2 O. sub. 3 in a concentration not exceeding 10 mole percent, and MXO in a concentration not exceeding 12 mole percent, wherein MXO is a metal oxide selected from the group consisting of PbO, BaO, CaO and MgO or a mixture thereof. This composition is suitable to hermetically seal to components for use in RF-interconnection applications.
