Microwave Devices and Circuits

Microwave, RF, Analog, and Digital

Microwaves, also referred to as "micro-kilowaves", are electromagnetic waves that have wavelengths approximately in the range of 1 GHz to 300 GHz, which is relatively short for radio waves.

Microwaves can be generated by a variety of means, generally divided into two categories: solid state devices and vacuum-tube based devices. Solid state microwave devices are based on semiconductors such as silicon or gallium arsenide, while vacuum tube based devices operate on the ballistic motion of electrons in a vacuum under the influence of controlling electric or magnetic fields.
