Everything You Need to Know About Solid State RF Switch
Are you familiar with solid state RF switch and are thinking about buying one? Familiarize yourself with everything you need to know about solid state RF switch.
Switches are important for providing control in RF and microwave systems. They help in turning power on and off and channeling signals from one branch of a circuit or a system to another. RF switches come in different shapes and sizes and are usually based on a number of technologies, various types of contacts by electromechanical functions etc. So what are solid state RF Switches?
Solid state RF switches are fabricated from CMOS or gallium Arsenide FET’s. RF switches that picker interfaces make use of CMOS switches. Read the following to have a better understanding about solid state switches.
Benefits
Solid state switches have very fast operating times and also have a very long operating life. Along with this RF switches are also capable of automatically terminating unused input signals in 500hms in order to reduce VSWR issues.The benefit of this feature is that it is useful for adding considerable extra cost. You should opt for these switches for low insertion loss and very high isolation is not required.
Why Are Solid State RF Switches Better Than Mechanical Switches
Solid state switches are better than mechanical switches since they provide various advantages such as long operating life, quick switching time, low power consumption and is smaller in size.
Along with this they also offer other benefits over mechanical switches such as higher isolation and better RF power handling capability
Solid state RF switches also have various disadvantages such as they are unable to handle as much RF power as their mechanical counterparts and cannot handle DC signals efficiently as well. However these drawbacks can be overcome by avoiding DC signals in your device. Along with this there is no denying that RF switches have some obvious benefits over mechanical switches making them a better choice.
Applications of Solid State Switches
Solid state RF switches can be used for a wide range of applications such as instrumentation. They are widely used in applications requiring signal levels beyond 20 dBm and products which are generally below 80 dBc.
For other applications such as wireless communication, radar test systems and many more such applications, solid state RF switches can be typically found.
There are various reputed companies that offer solid state switches, but it is important to first assess your requirement before purchasing RF solid state switch. Choose a design that offers excellent performance and a range that includes a programmable attenuator.
