A hermetically sealed enclosure, or hermetic packaging, is a method of encapsulating a device or system in an environmentally protected package that prevents the exchange of the inside and outside environment. Hermetic packages are commonly seen in automotive, industrial, naval, military, and aerospace applications where the outside environment may lead to damage, early failure, or ..

Harmonics are spurious signal content (or spurious emissions) that are generated by a single frequency tone and nonlinear elements within a RF/microwave signal chain, or single-tone intermodulation distortion (IMD). The nonlinear elements create harmonics that are integer multiples of the fundamental frequency (often called the first harmonic). For instance, fo is the fundamental frequency and ..

There are several key methods of describing RF signal quality and device performance in respect to noise and linearity. As noise and linearity are often key considerations of both transmit and receive chains in communications and sensing systems, it is valuable for a technical professional to understand these parameters. The following is a brief description ..

It may be surprising to some that low power system and device/component design share many of the same considerations as high power system design, albeit for different reasons. The goal of low noise design is to limit the amount of added noise, harmonics, spurs, and other factors that increase the noise floor of a signal ..
