Abstract

A housing for accommodating a microwave device having an insulating cup member.

Claims

1. A housing for accommodating a microwave device, comprising:

a metallic base member having a lower portion, and having a top and bottom surface, a central pedestal member extending from the top surface, said pedestal member having a device top surface for accommodating said microwave device;

an insulator cup member having an open top, side walls, and a bottom surface, the bottom surface extending from the side walls, and having a pedestal accommodating aperture in said bottom surface, said pedestal accommodating aperture having a width less than the width between said side walls, with said cup member being of a greater height than the height of said pedestal member, to cause said cup to laterally surround said pedestal when said pedestal is inserted through said aperture.

2. The housing of claim 1, wherein said insulator cup member comprises a ceramic cup member.

3. The housing of claim 1, wherein said open top surface of said cup member has a metallic layer deposited above a peripheral edge thereof.

4. The housing of claim 1, further comprising a cover member secured to a peripheral edge of said open top to enclose said microwave device when accommodated on said pedestal top.

5. The housing of claim 1, wherein said pedestal includes a substantially cylindrical first portion and a tapered second portion.

6. The housing of claim 1, wherein said base member is fabricated from copper.

7. The housing of claim 1, wherein said base member comprises a nickel-cobalt ferrous alloy.

8. The housing of claim 2, wherein said ceramic cup member is fabricated from at least one of alumina ceramic and beryllium oxide.

9. The housing of claim 2, wherein said base member is secured to said ceramic cup member by a ceramic to metal seal.

10. The housing of claim 1, wherein the bottom surface of said base member has a peripheral flange.

11. The housing of claim 1, wherein said cup member, said base member and said pedestal are all coaxial.

12. The housing of claim 1, wherein said bottom surface of said cup member has a metallic layer deposited thereon, and said metallic layer is suitable for coupling to the top surface of said base member.

13. The housing of claim 1, wherein said metallic base member lower portion is substantially cylindrical.

14. The housing of claim 1, wherein said cup member comprises one of a sapphire and quartz material.

15. An electronics package comprising:

a hollow elongated member having a closed end, side walls, and an oppositely disposed open end, the closed end extending from the side walls, and forming an interior recess, wherein said closed end terminates in a substantially central aperture whose width is less than the width between said side walls;

a tapered support extending through said aperture and into said recess;

at least one electronic component secured to said support within said recess; and

,

a closing member secured over said open end of said elongated member.

16. The package of claim 15, wherein said elongated member comprises a ceramic cup.

17. The package of claim 15, further comprising a metallic base member external to said recess securing said pedestal to said elongated member.

18. The package of claim 17, wherein said closing member is substantially the same size and shape as said base member.

19. The package of claim 15, wherein said tapered support provides at least one electrical contact for said at least one electronic component.

20. The package of claim 19, further comprising a metallic coating on a periphery of said open end, wherein said metallic coating provides at least a second electrical contact for said at least one electronic component.

21. The package of claim 15, wherein said at least one electronics component is selected from the group consisting of:

a Gunn device, an avalanche diodes, a Schottky diode and an amplifier.

22. The package of claim 15, wherein said at least one electronics component is a microwave device.
