RF MEMS switches are small, micromechanical switches that consume little power and can be produced using conventional MEMS manufacturing techniques. They are similar to a light switch in a room, where contacts open or close to conduct a signal through the switch. In the case of RF MEMS devices, the mechanical components of the switch are only micrometer-sized. Unlike a light switch, the signals conducted in an RF MEMS switch are in the radio frequency range.

This is a different technology from both electromechanical and solid-state RF switches.

Solid-state switches operate using semiconductor technologies such as silicon or PIN diodes, FETs (field effect transistors) and hybrid technologies (combinations of PINS and FETs) and are built using silicon-based substrates. RF MEMS switches compete with the ever-improving RF-SOI (Silicon on Insulator) based switches, which are the dominant solution in the market today.

The above content is excerpted from Talking about RF MEMS . It is really very clear. After reading it, I found that such a profound technology can be explained so simply.

I have a friend who is working on MEMS in college and does simulation every day.

Many things can be simulated with software, which is very convenient.

I don't understand the details of micro-electromechanical systems, fluids, and heat, and I can't understand them.

Yes, it looks complicated...
