AFT05MS004N RF Transistor

Hi,

About the AFT05MS004N, page 17 on his datasheet, the impedance table does not correspond to the ploting on the smith chart.

Hello JP,

I hope all is great with you.

The impedance table is correct. Please note that Zo is 5Ω.

I mean, Z = (R + jX) = (0.45 + j0.35)*5 = 2.27 – j1.72

I hope this information helps.

Regards,

Hi,

I do not completely agree with your multiplication, and usualy we plot positive j on top.
The problem is for the load side where we have positive and negative value for j on the chart, and always positive on the table.
