Abstract :
The proliferation of 2.4 GHz wireless standards such as Bluetooth and IEEE802.11b makes it desirable to realize low-power, compact transceivers capable of interoperability between frequency-hopping and direct-sequence systems. While Bluetooth requirements for receiver sensitivity and phase noise and transmitter linearity are relatively relaxed, those of IEEE802.11b are much more stringent. This paper describes a transceiver targeting both standards. The frequency planning and the design of all of the building blocks achieve low power dissipation for the overall system (while accommodating a GPS input in future implementations).
