Hi,

I would like to ask some questions on the ADL5243. Earliest replies would be appreciated.

Please refer to the ADL5243 datasheet , Rev. B.

 

Q1: NC pins

In Table 3. It is said NC pins should not be connected , but they are connected to GND in Figure 58.

Which is correct?   ( Connecting to GND seems correct and better , but let me confirm it.)

 

Q2. DSA insertion loss at 2630MHz

Does  the spec. -2.8 dB for  the insertion loss include the return loss ?

 

Q3: LOOP FREQUENCY at 2630M

1) Does the spec.  29.5 dB  for GAIN include the DSA insertion loss?

2) Does the spec.  24.6 dB  for output P1dB  include the DSA insertion loss? 

 

Best Regards,

Lux
