上海交大射频集成电路RFIC-System-Overview
资料介绍
Advantages aIntegration of channel filters is possible
. Less susceptible to 1/f noise and DC offsets (AC coupling)
aLow-frequency IM2 product can be easily blocked.
Disadvantages aImage is still a problem, which entails precise l/Q match
. Complex signal processing is essential to obtain necessary selectivity
Advantages
.Digital signal process avoids the problem of /Q mismatchl
.Less susceptible to process variations Disadvantages
·ADC performance is a great concern
Advantages
. The PLL LPF to suppress out-of-band noise(no need for bulky off-chip SAW filter
. Accurate phase shift is eaiser at lower frequency Disadvantages
. Enough isolation is still required to suppress LO pulling
. Only constant envelop modulation scheme is allowed
. Wide power control dynamic range is not easily obtained
