Abstract
The wireless up-stream industry of GaAs material had experienced the Procomm event in 2004.The smart phone and the tablet computer market increased since 2010. The demand on power amplifier (PA) chips for cell phone and the tablet computer also increased and it lead the shortage on PA production quantity. When the mobile communication technology standard upgraded from 3G to 4G, it became more difficult to develop on RF front end solutions. For PA, the mobile device had faced the problem on price pressure, device volume, and power consumptions. The linearity and efficiency have more strict requirements and increased the technology complexity. It became an important issue about facing the competition in oligopoly market for wireless up-stream industry of GaAs material. This research focused on case study to discuss the product and technology strategy of individual company by Mike Porter’s 5 forces and STP analysis. The suggestions for this research are as below. - Core products: To improve on cost control - New products: Establish the knowledge/skill for mass production - New technology: Ensue to have successful development on new technique and establish the knowledge/skill for mass production.
