Abstract

A fully integrated front-end IC is demonstrated for 802.11b/g transceivers with integrated power ampli ﬁers. The SP3T-LNA architecture integrates Bluetooth® functionality with transmit and receive for wireless LAN. The transmit switch achieves a P greater than 33.0 dBm at 2.5 GHz by employing a cross-biasing approach, transistor stacking and deep n-well process. Power handling techniq ues used for the switches and the associated performance tradeoffs are discussed. The measured noise ﬁgure of th
