        S-TEK main business scope is radio-frequency IC and analog/mixed signal IC designs which are focused on the development of high frequency communication ICs, RF modules, for applications such as CDMA, Opto-Electronic Integrated Circuit (OEIC), Wireless LAN, VSAT, point- to-point radio, direct TV satellite receiving, LMDS and electronic traffic control as well as automotive electronics, etc. Main products are as following:
1.  MMIC products
        Our main MMIC products cover RF T/R front-end chips such as PAs, LNAs, switches, and many other chips, which are based on world-leading GaAs, SiGe, as well as RF CMOS foundry processes. For GaAs MMICs advanced 0.25um or 0.15um PHEMT (including power, low noise) as well as 2um HBT technology has been used. 
       Major MMIC products and related applications are listed in the following:

MMIC products   MMICs-PAs   MMICs-LNAs   Other MMICs
