Definition

Compact peripheral component interconnect (CPCI) is an adaptation of the peripheral component interconnect (PCI) specification for industrial computer applications requiring a smaller, more robust mechanical form factor than the one defined for the desktop. CompactPCI is an open standard supported by the PCI Industrial Computer Manufacturer's Group (PICMG). CompactPCI is best suited for small, high-speed industrial computing applications where transfers occur between a number of high-speed cards.

It is a high-performance indust ....etc

Compound solid state switches such as GaAs MESFETs and PIN diodes are widely used in microwave and millimeter wave integrated circuits (MMICs) for telecommunications applications including signal routing, impedance matching networks, and adjustable gain amplifiers. However, these solid-state switches have a large insertion loss (typically 1 dB) in the on state and poor electrical isolation in the off state. The recent developments of micro-electro-mechanical systems (MEMS) have been continuously providing new and improved paradigms in the field ....etc

How would you like to be able to energize any electrical device in your home., from any where in the world. and do it without paying for a telephone call? You can do it and it's perfectly legal. With the Telephone Triggered Switches you can do just that. The device described here is a circuit, which responds to the sound of the telephone Deli There is no need to make any hard wire connections to the telephone line, and it is this feature which permits you to build and use this device without any permission from the Department of Telecommunicati ....etc

ABSTRACT
A surface micro machined capacitive switch has been designed and fabricated on a glass substrate. The switch is constructed of a thin metallic membrane crossing over an electroplated coplanar wave-guide transmission line. The electrostatic actuation is utilized as the switching mechanism. The actuation voltage is around 50V. The switch showed low insertion loss of 0.1 dB at 10 GHz and 0.4 dB at 25 dB, and isolation of 15dB at 20GHz. This device offers a potential application in tel ....etc

ABSTRACT

Switching products technologies ranges from traditional Electro Mechanical Relays (EMR) and reed relays to semiconductor switches made of silicon or GaAs materials. A new type of device is currently getting to commercialization. The first sales of RF MEMS switches outside DOD programs have been realized by Teravicta in 2006. The achievements of RadantMEMS in USA DOD programs, the first commercial product sales from Teravicta in 2006 and the 4 other competitors (MEW, XCOMwirel ....etc
