Solid State RF and Microwave Switches
The Solid State RF and Microwave Switches have the following advantages over mechanical switches; long operating life, fast switching time, low power consumption and small size. Mechanical RF and Microwave Switches usually have lower insertion loss, higher isolation and higher RF power handling capability. However, because of the advantages mentioned above, Solid State RF and Microwave Switches are to prefer if very low insertion loss and/or very high isolation is not needed.

Waveguide Switches
Waveguide switches are electromagnetic switches with hollow circular or rectangular cross-sections and are used for routing RF energy in microwave communications, broadcasting, and in radar applications. Waveguide switches can be used to transfer both power and communication signals, and the bandwidth of a waveguide is in relation to its size, and thus always referred to by its size (e.g. WR112, WR90, WR75 etc.). Compared to coaxial switches, waveguides can route extremely high power signals over a narrow bandwidth at low to high frequencies, and now Lightweight Waveguide series is available.

High Power Switches
MPG Switch line of High Power RF & Microwave Switches fit applications where electromechanical switches fail to meet the size, cost and speed of project specifications. At microwave frequencies, a high power switch acts as a current-controlled resistor, allowing current to flow in a single direction. When forward biased, the switch relay behaves as a closed circuit, but when the current is reverse biased, the RF switch becomes an open circuit.
