A RF switch matrix consists of multiple RF switches, switch driver circuits, a power supply and a housing. It allows the remote-controlled routing of RF signals between multiple input and output connectors. Two types of switches are generally used: electro-mechanical and solid state or electronic switches. Advantages of electro-mechanical switches compared to electronic switches usually arelower insertion loss, better VSWR, higher isolation specifications and higher RF frequencies. Vice-versa electronic switches compared to electro-mechanical switches provide usually the following advantages much longer life time, higher switching speeds and higher repeatability.
