a datasheet of SiRF about GPS,and I think have some errors
wish u can give some option about mine.
I think there are some errors in page 20 , the smith chart give the value of point 1 ,point2,and point3
do u think the value of point2 and point3 's imaginary value is right?
i think it should change to pint2: 12.25 -j 72.16Ω and point3 : 27.81 - j 59.24Ω
I too agree that ther is typo error.
If point 1 is correct then point 2 and 3 are wrong and vice versa.
This is because all the points are -ve or positive if complex conj is applied.
Added after 21 minutes:
I did some basic simulations and conclude that it should be -ve only
