Today, as frequencies increase, so does the pressure to reduce form factors and footprints. This is the driving force behind MEMS, and the movement it starting to target mm-wave devices.
By Rich Chen
The growth of the wireless communication industry has strengthened interest in millimeter-wave circuits. As the frequencies of these circuits have increased, the size of the devices has decreased. Radio frequency devices that were once manufactured with machining techniques need new methods for fabrication because of their relatively small dimensions.
