A fully packages variable optical attenuaror based on a MEMS silicon chip is shown to have low insertion loss, low PDL, a flat response over 1530nm-1565nm, and a low DC drive voltage.
A 64-channel 14 GHz-spaced MEMS-based filter has been constructed.
This paper presents the implementation and test of prototype RF MEMS based voltage controlled oscillators (VCO) for space applications.
A layered structure including a variable air gap or gaps is appropriately thought of as a dielectric stack whose optical properties can be driven.
In order to controllably alter the passage of light, which is a succinct description of the function of a dynamic passive optical component, something must move, whether it be the electron wave fun
When capacitor paper is subjected to electrical stress, large variations in durability are noted from lot to lot.
Fixed wireless systems are designed to provide broadband connectivity to residential and enterprise customers.
For parallel independent Gaussian-noise channels with an aggregate power constraint, independent Gaussian inputs whose powers are allocated according to the waterfilling policy maximize the sum mut
Traditionally, the problem of indoor tracking is solved by using some non-RF ranging technologies (such as infrared or ultrasound).
In a cellular radio, as in any system, the architecture determines the quantity and quality of bipolar and BiCMOS content.
