monolithic microwave integrated circuit (MMIC)

As can be seen from the name Monolithic Microwave Integrated Circuit (MMIC), it is a monolithic technology with which microwave integrated circuits can be manufactured. An MMIC can contain both passive and active microwave components. The frequency range of application extends from high-frequency technology to microwaves of 300 GHz.

MMICs include complete RF circuits with microwave amplifiers, low- noise amplifiers( LNA), mixers, and filters. The input impedances and the output impedances of MMICs are matched to the impedance of 50 ohms commonly used in microwave technology. MMICs are used in microwave equipment, radios, satellites and radar systems.

Monolithic Microwave Integrated Circuits have been continuously miniaturized. While they were first integrated circuits with microstrips, the development went over the much smaller uniplanar MMICs to MMICs as 3D-ICs with a size between about 1 qmm up to 10 qmm. In order to be able to process high microwaves, MMICs are often made of gallium arsenide( GaAs), which has significant advantages over silicon( Si) and silicon germanium( SiGe) in terms of ultrahigh frequencies and especially voltage.
