Matrix Switches, or Switch Matrices, are devices that enable the routing of RF signals through selectable paths. These devices can be as simple as single-input with two selectable outputs or as complex as having tens of inputs and outputs that can all be interested as needed. Switch Matrices are often used in test equipment setups ..

An RF Signal Generator is another keystone piece of RF test and measurement equipment, alongside spectrum analyzers and network analyzers. The purpose of signal generators is to create RF signals at varying power levels, frequencies, and in the case of vector signal generators, with various phase and waveform characteristics. RF signal generators are used in ..

Network Analyzers, and Vector Network Analyzers (VNAs), are one of the cornerstone RF test instruments, and virtually every test center or lab usually employs some type of VNA. These test instruments are able to send electromagnetic energy into a component, device, antenna, assembly, etc. and accurately measure the power transmitted and reflected through the device-under-test ..

The term “substrate” can be somewhat confusing the context of RF/Microwave devices, components, and applications. A substrate can generally be anything from the insulative material used to develop a semiconductor or film (thick-film or thin-film circuits or components), or the structural material of printed circuit boards (PCBs). These electrically insulating materials are the backbone of ..
