Abstract :
A small single-chip PHS RF front-end GaAs MMIC operating with single +3V supply voltage has been developed. This MMIC integrates transmitter power-amplifier, receiver LNA, switchable attenuator, RX/TX switches, and control logic in a single-chip. Unlike conventional GaAs MESFET technology, the new power GaAs MESFET incorporated in this chip does not require negative voltage gate bias, and as a result, the MMIC can be operated by a true single-supply voltage without internal or external negative voltage generator.
