A radio-frequency microelectromechanical system RF MEMS is a microelectromechanical system with electronic components comprising moving sub-millimeter-sized parts that provide radio-frequency RF functionality. Each of the RF technologies offers a distinct trade-off between cost, frequency , gain , large-scale integration , lifetime, linearity , noise figure , packaging , power handling , power consumption , reliability , ruggedness, size, supply voltage , switching time and weight. RF MEMS switches, switched capacitors and varactors are classified by actuation method electrostatic , electrothermal, magnetostatic , piezoelectric , by axis of deflection lateral, vertical , by circuit configuration series , shunt , by clamp configuration cantilever , fixed-fixed beam , or by contact interface capacitive , ohmic.

A Tunable Capacitor Based on MEMS Technology for RF Applications

A tunable capacitor based on MEMS technology is presented in this paper. The proposed structure consists of two fixed-fixed parallel movable plates with 4 supports. Movability of two plates makes it possible to actuate the plates with a small voltage. When the actuation is applied, two plates move together and their distance is decreased, hence the capacitance is increased and tuning is achieved. The quality factor is 91 at 11 GHz which is sufficient for various RF communication applications such as filters, transceivers and so on. The low stress induced on the plates and low actuation voltage, are the main advantages of the design. Krauss, C.

Radio-frequency microelectromechanical system

This paper reports material selection methodology for radio frequency - micro electro mechanical systems RF-MEMS switches used for reconfigurable antennas. As there are variety of materials available to design engineer, a proper technique to select the best possible material is needed. Three primary performance indices, pull-in voltage, RF-loss, and thermal residual stress, are used to obtain the desired performance.

RF MEMS: Theory, Design and Technology

Теперь же он был рад, что проделал это, потому что на мониторе Сьюзан скрывалось что-то очень важное. Задействованная ею программа была написана на языке программирования Лимбо, который не был его специальностью. Но ему хватило одного взгляда, чтобы понять: никакая это не диагностика. Хейл мог понять смысл лишь двух слов. Но этого было достаточно. СЛЕДОПЫТ ИЩЕТ… - Следопыт? - произнес .

 - Она еще раз взглянула на текст.  - Элементы, ответственные… У Дэвида Беккера, находившегося в трех тысячах миль от комнаты оперативного управления, загорелись. - Элементы! - воскликнул.  - Мы говорим о математике, а не об истории.
