The MRFIC1819 and MRFIC0919 are single supply, RF Integrated Power Amplifiers (IPAs) that are designed for use in 900 MHz, and 1.8 to 1.9 GHz cellular phones respectively. These Gallium Arsenide three-stage IPAs both have an integrated on-chip negative voltage generator, with Gate-Drain priority switching that protects the GaAs power amplifier. These second generation features are implemented using RF rectification, which prevents the generation of any spurious signals.
