RF Glossary: M | Terms Starting with M

Matching Network — A circuit that transforms impedance from one value to another to maximize power transfer between source and load.

Microstrip — A planar transmission line consisting of a conductor strip on a dielectric substrate with a ground plane on the opposite side.

Mixer — A nonlinear device that combines two input frequencies to produce output signals at the sum and difference frequencies.

MMIC (Monolithic Microwave Integrated Circuit) — An integrated circuit fabricated on a semiconductor substrate that performs microwave frequency functions like amplification, mixing, or switching.

Mode — A specific pattern of electromagnetic field distribution that can propagate in a waveguide or resonate in a cavity.

Modulation — The process of encoding information onto a carrier wave by varying its amplitude, frequency, phase, or a combination thereof.

Multiplexer (MUX) — A device that combines multiple signal channels onto a single transmission path, typically using frequency division.

Mutual Coupling — The electromagnetic interaction between adjacent antenna elements or transmission lines that affects impedance and radiation pattern.
