SEMICONDUCTOR APPARATUS

摘要

A semiconductor apparatus for effecting a plurality of functions involving high frequency signals and low frequency signals includes: (a) at least one first circuit section implemented in at least one first semiconductor material; and (b) at least one second circuit section implemented in at least one second semiconductor material. The at least one second semiconductor material exhibits lower noise generating characteristics than the at least one first semiconductor material at the low frequency signals. The at least one first circuit section and the at least one second circuit section are implemented in an integrated circuit construction. Preferably the integrated circuit construction is a monolithic configuration. Preferably the at least one first semiconductor material includes gallium arsenide. Preferably the at least one second semiconductor material includes silicon.
