RF Electromechanical switches are a key active device in many signal chains, including time-domain duplex communications and pulsed radar applications. Such switches can be as simple as a 3-port toggle switch, or single pole double throw, or more complicated as double pull switches or single pole switches with more than 10 poles. A main benefit ..

Both RF limiters and Attenuators reduce the power of an RF signal. However, they do so in different ways that are key to understanding their use. These components are often used to protect sensitive RF components and devices.There are also a wide range of RF limiters and attenuators that also operate various ways that may ..

Though both often dubbed as “dividers”, frequency dividers and power dividers perform very different functions. Where a power divider splits an input signal power to two or more output ports, a frequency divider actually outputs a frequency that is a fraction of the input frequency. A frequency divider should not be confused with a diplexer ..

It has been understood for nearly a century that the conductivity of conductive metals changes as a function of frequency. Though this is the case the phenomenon behind frequency dependent conductivity is not as well understood by man. It was observed early on that the attenuation and resistive losses of metallic transmission lines and traces ..
