    摘要: A high frequency microelectronic package suitable for high-frequency microelectronic devices includes a base which is at least partially conductive and attached to an RF substrate with a cavity formed at its center. The base may be metal or ceramic with a metal layer deposited thereon. A pattern of conductive paths for providing interconnection from the inside to the outside of the package are formed on the surface of the RF substrate. These conductive patterns are designed to have a constant impedance when uncovered, regardless of the dielectric property of the material used to cover the conductive patterns. Namely, a sealing cap or a lid, made from a variety of dielectric materials, may be attached to the RF substrate by a non-conductive adhesive, such as a polymer adhesive or low temperature seal glass, to seal the package once the microelectronic device has been mounted inside.

    摘要: A ceramic microelectronic package suitable for high-frequency microelectronic devices includes a base which is at least partially conductive attached either by seal glass or by solder to a ceramic RF substrate with a cavity formed at its center and a pattern of conductive paths for providing interconnection from the inside to the outside of the package. The base may be metal or ceramic with a metal layer deposited thereon. A ceramic seal ring with a second cavity corresponding to that of the RF substrate, but slightly larger, is attached to the RF substrate by seal glass which is patterned to generally match the dimensions of the seal ring. A ceramic lid is attached to the top of the seal ring by a non-conductive adhesive, such as a polymer adhesive or low temperature seal glass, to seal the package once the microelectronic device has been mounted inside.

    摘要: An integrated circuit for use in fiber distributed data interface (FDDI) system has four elastic layer and buffer management (ELM) circuits (12, 14, 16, and 18) coupled through a crossbar switch (20). The crossbar switch (20) allows any of the ELM circuits (12, 14, 16, and 18) to be coupled to any other ELM circuit (12, 14, 16, or 18) or to one of three external buses for FDDI communication. By using a crossbar switch and four ELM devices on a single integrated circuit, FDDI performance is improved while system design is made easier and more flexible than previously possible. Cipher circuitry (22, 24, 26, and 28) is used to scramble and descramble data ingoing and outcoming from the ELM devices. Concentrators, workstations, local area networks (LANs), and the like may incorporate the circuit (10) to improve performance and flexibility.
