WIN Semi Releases New GaAs PHEMT Platform
WIN Semiconductors, a Taiwanese pure-play compound semiconductor foundry, is expanding its portfolio of highly integrated GaAs technologies with a new pHEMT technology which incorporates monolithic PIN and vertical Schottky diodes with WIN's high performance 0.1Âµm pseudomorphic HEMT process, PP10.
This integrated platform, PIH0-03, adds a highly linear vertical Schottky diode with cut-off frequency over 600GHz, as well as multi-function PIN diodes while preserving the state-of-the-art mmWave performance of the PP10 technology. The availability of monolithic PIN and Schottky diodes with a high performance mmWave transistor enables on-chip integration of a wide range of functions, including mixers, temperature/power detecting, limiters, and high frequency switching, and supports power, low noise and optical applications through100 GHz.
This integrated technology provides users with multiple pathways to add on-chip functionality and reduce the overall die count of complex multi-chip modules used in a variety of end-markets. In addition to high frequency switching, the monolithic PIN diodes can be used for low parasitic capacitance ESD protection circuits, and as an on-chip power limiter to protect sensitive LNAs in phased array radars. The vertical Schottky diodes enable numerous detecting and mixing functions and can be combined with the PIN diodes in unique limiter applications.
"Today's complex systems and highly competitive markets require increased mmWave performance and more functionality per chip. The PIH0-03 platform is the latest example of how WIN Semiconductors is addressing these critical market needs by offering high performance GaAs technologies with new levels of multifunction integration. To meet the ever-increasing demands of next generation mobile user equipment, wireless infrastructure, fiber optics and advanced military systems markets, WIN Semiconductors continues to commercialise advanced, highly integrated GaAs solutions and provide our customers a clear technology advantage," said David Danzilio, senior VP of WIN Semiconductors
