GaAs vs SiGe round two: auto radar?

摘要

It is surprising to discover how many new applications there are for SiGe, and they are by no means restricted to RF amplification. A survey of the literature throws up all manner of exciting device applications, showing how much potential still exists in the SiGe semiconductor family. The biggest market may be yet to come, that of 'auto radars' - RF sensors in vehicles - which would, however, be yet more RF amplifiers.
