DESCRIPTION

The START620 is a member of the START family

that provide market with the state of the art of RF

silicon process. It uses ST’s Silicon Germanium

technology. This technology offers ft’s of up to

45GHz and Fmax’s of over 60GHz. The START620

offers the best mix of gain and NF for given

breakdown voltage(BVceo = 3.3V).

It reaches performance level only achieved with

GaAs products before.
