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
