We have a good experience in some of the principals RF blocks.
Phase noise is better than what we could measure at that time.
Simulations showed -115 dBc/Hz @ 100 KHz. We recently measured about -110dBc/Hz @ 100 KHz (non ideal conditions).
EM simulations are essentials to predict package parasitic and obtain a functional packaged CI.
Nowadays, a lot of applications focus on low power.
This receiver only consume 850 uW for a 20 dB conversion gain at 2.4 GHz (CMOS 0.13 um).
