Abstract
Bluetooth headsets demand high radio performance at extreme low power consumption. A Bluetooth (BT) transceiver implemented in a 0.5 μm BiCMOS process is supplied at 1.8 V and consumes less than 24mA when receiving and less than 18mA when transmitting. The receiver has -91dBm sensitivity and best-in-class blocker performance. Architecture, circuits and radio performance are reviewed. A Bluetooth headset based on this transceiver consumes 12mA in a 64kb/s HV3 voice link, has 10h talk time and weighs only 14g.
