Abstract :
A 2.4 GHz transmitter architecture exploits the combination of an SSB up-converter mixer and a truly co-designed PA and BAW resonators to achieve a clean output spectrum and efficient transmission. Integrated in 0.18 ¿m CMOS, it demonstrates a maximum output power of 5.4 dBm and a suppression of all the unwanted components of more than 40 dB, while consuming 42 mW from a 1.2 V supply.
