Hi, everybody,
I have read an interesting market infomation of RF PA technology, in an isscc2004 tutorial. which said that 73% of commerial PA (in mobile) is in GaAs, 20% in LDMOS.
But as we know, in recent years, since SiGe technology is rising up, the PA market may have changed. How can i get some new marketing infos about this? Is there anyone who can told me some links or infos. thanks a lot.

There are few semiconductor manufacturers which already released low power RF amplifiers made in Silicium-Germanium process (SiGe Semiconductor, M/A-Comm, Maxim, Atmel, etc).
The biggest problem designing RF power amplifiers in SiGe is the ruggedness, due to low break-down voltage of the process.
