A MMIC 2.4 GHz transmitter and 5.78 GHz receiver for wireless LAN applications

Monolithic microwave integrated circuits (MMIC) technology using GaAs offer high performance and very low cost for the production of Wireless-LAN IC components. This paper reports the development of a 2.4 GHz transmitter and a 5.78 GHz receiver. The transmitter upconverts a 360 MHz frequency, applying a gain of 50 dB, with 24 dBm output. The receiver downconverts to 180 MHz and has 50 dB gain and a 4 dB noise figure (NF).
