Abstract :
This paper will present a generic digital transceiver system and discuss factors involved in the partition and development of an ASIC solution. The results of such a development will be discussed. Included is an ultra-low power consumption LNA (1.7 dB NF @ 3 V, 2 mA), a high power added efficiency PA chain (44% @ 0.25 W), a low distortion T/R switch (OIP3>44 dBm with two 0.25 W tones), precise adaptive power control with a digital attenuator and DC power efficient up and down converter functions
