Abstract

This paper presents the design and measurements of a receiver front end dedicated to IEEE 802.11a WLAN applications. It consists of an integrated transformer, a low noise amplifier (LNA), a mixer and a synchronous oscillator (SO) as a frequency generation device. This front-end has a gain of 22 dBV at 5.2 GHz and a good trade off between its linearity and its current consumption with an ICP1 of -17 dBm and a power consumption of 75.4 mW. The intermediate frequency is fixed at 100 MHz. This receiver front-end has been fully integrated within a 0.25 μm SiGe BiCMOS technology from STMicroelectronics.
