What's the Best Wireless Transport Option for Uncompressed HDTV Video

Once the exclusive realm of scientific research and military use, wireless systems operating in the upper millimeter wave (MMW) regions are now providing cost-effective solutions for high-capacity commercial data transport needs. While MMW technology is nothing new, the growing volume of commercial use with associated economies of scale has significantly reduced system costs, making MMW systems more attractive to the general consumer.

eSMA Connector Technical Overview

This one page technical overview includes cut away descriptions of the mechanical engineering behind this innovative high-performance SMA. Additionally, performance curves are analyzed for typical VSWR through 20 GHz.

Ultra Low Noise Amplifiers for Infrastructure Receiver Applications

Amplifiers used in wireless infrastructure receiver applications have the key requirements of low noise, high linearity, and unconditional stability. In order to meet these needs, Skyworks has developed a new family of low noise amplifiers (LNAs) implemented in 0.5 μm enhancement mode (E-Mode) pHEMT.

Application Guide to RF Coaxial Connectors and Cables

There is a wide variety of coaxial connectors and cables available for use in the RF and Microwave spectrum. While often not much thought is given to these essential components, a misstep here can result in undesirable system degradation.

The Pros and Cons of Dual-Band RF Amplifiers

In an effort to cover the relatively broad frequency ranges mandated by most modern EMC immunity standards, some amplifier vendors have resorted to combining two amplifier modules within a common enclosure. These so called dual-band amplifiers use frequency band switching to achieve an overall broader frequency band than either amplifier module could cover by itself. This application note will highlight both the benefits and drawbacks of this technique.
