A GaAs based high performance transceiver front-end chipset for 5-6 GHz wireless applications

This paper presents the development of a high performance broadband transceiver front-end chipset for 5-6 GHz wireless applications in a commercial GaAs MESFET process. The developed chipset include a power amplifier, mixer, VCO and LNA.. The developed chipsets are compliant to the IEEE 802.11a wireless LAN standard. The power amplifier shows a power gain of 14 dB, an output 1 dB compression power of 24 dBm, the LNA exhibits a 13.5 dB gain, 2.2 dB noise figure and an IIP3 of 2.8 dBm. The performances of the developed chipsets show significant linearity improvement over earlier implementations.
