Nothing, compared to the growth it's going to see with POET.
The Information Network notes that GaAs power amplifiers will continue to lose market share to silicon-based CMOS (complementary metal oxide semiconductor), but will remain the dominant RF technology in the foreseeable future. In particular, pricing for PAs has risen from $0.30 per 2G handset to $1.25 per 3G handset and $3.25 for global long-term evolution (LTE) technology, adds the report.
