Bead (L21):

Recommend to reserve R106, R110, R109

to filter noise from demod side.

IF trace shielding by GND

IF Interface Filter

I2C Interface Filter

- R103 and R106 are related to Demod side's

IFAGC design. Sometime need to  fine tune

for different Demod.

- Following IFAGC TBD table is common

suggestion.

供电范围:

3.13~3.47V

(1) +VDD3V input voltage tolerance must be under +-5%
(2) +VDD3V input ripple must be under 30mVpp
(3) Using LDO for +VDD3V is recommended

Bead (L21): 

1k@100M &

方案,

AGC

采用电流型输出,
