March 5, 2012 — HRL Laboratories LLC will now offer products in its gallium nitride (GaN) high electron mobility transistor (HEMT) technology commercially to customers in select markets, such as high-data-rate wireless links, radars and active sensors.
HRL’s GaN amplifiers offer more than 5x improvement in E and W-band output power compared to current state-of-the-art commercial solid-state technologies, the company reports. The transistors minimize the power module assembly complexity by eliminating power-combining multiple amplifiers. GaN also boasts intrinsic higher linearity for transmission of modulation schemes with higher spectral efficiency.
