2. Microwave engineering - Wikipedia

   en.wikipedia.org/wiki/Microwave_Engineering

   Specialties include microwave and RF integrated circuit design, antenna engineering, computational electromagnetics, radiowave propagation, radar and remote sensing systems, image processing, and THz imaging. [5] [6] Tufts University offers a Microwave and Wireless Engineering certificate program as part of its graduate studies programs. It can ...

3. Monolithic microwave integrated circuit - Wikipedia

   en.wikipedia.org/wiki/Monolithic_microwave...

   Monolithic microwave integrated circuit, or MMIC (sometimes pronounced "mimic"), is a type of integrated circuit (IC) device that operates at microwave frequencies (300 MHz to 300 GHz). These devices typically perform functions such as microwave mixing , power amplification, low-noise amplification , and high-frequency switching.

4. Microwave transmission - Wikipedia

   en.wikipedia.org/wiki/Microwave_transmission

   Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter , but such systems are expensive and generally used only in ...

5. Circulator - Wikipedia

   en.wikipedia.org/wiki/Circulator

   ANSI and IEC standard schematic symbol for a circulator (with each waveguide or transmission line port drawn as a single line, rather than as a pair of conductors). In electrical engineering, a circulator is a passive, non-reciprocal three- or four-port device that only allows a microwave or radio-frequency (RF) signal to exit through the port directly after the one it entered.

7. Isolator (microwave) - Wikipedia

   en.wikipedia.org/wiki/Isolator_(microwave)

   At microwave frequencies, this material is usually a ferrite which is biased by a static magnetic field [1] but can be a self-biased material. [2] The ferrite is positioned within the isolator such that the microwave signal presents it with a rotating magnetic field, with the rotation axis aligned with the direction of the static bias field.
