Abstract :
A fully integrated RF transceiver and power amplifier for 5.8 GHz frequency band operation are presented. The transceiver is composed of a low noise amplifier, low-IF receiver, digital demodulator, fully integrated VCO, PLL, transmitter and 2 dBm output amplifiers. For typical applications in transmit mode, a subsequent 25 dBm power amplifier (PA) is integrated. The PA and the transceiver are fabricated using Atmel´s SiGe and SiGe BiCMOS technology, respectively. The transceiver and PA operate from a single lithium battery, avoiding mechanical tuning. The number of external components is drastically reduced compared to previous solutions.
