Hi all,

Our customer will start to evaluate the AD8341.
They have a question about I/Q baseband input level/common mode level.

 

Please let me know if my understanding is correct.

 

In a differential fashion,
 Common mode level:250 mV to 750 mV (typ 500mV)
 Input swing:±0.5 V differential

 

In a single-ended fashion,
One side is;
 Common mode level: 500mV typ ? (250 mV to 750 mV is available ?)
 Input swing:0.0 V
Other side is;
 Common mode level: 500mV typ ? (250 mV to 750 mV is available ?)
 Input swing:1.0 Vp-p single-end (0 V to 1 V swing)

 

Best Regards,
sss
