AlGaAs Technology

Bandgap Engineering has been used to produce novel semiconductor structures in the  microwave industry for over two decades. Utilizing the properties of multiple quantum wells, superlattices, and heterojunctions, a new class of semiconductors grown by molecular beam epitaxy and metalorganic vapor phase epitaxy has been created. These band gap principles have been applied to the development of MACOM’s AlGaAs technology resulting in a significant advancement in the RF performance of PIN diodes.
