Post by sivacha on Oct 25^th, 2006, 3:16am

hi experts,

i am facing some difficulty in measuring the iip2 of the mixer.
it is not clear to me how to choose the second harmonic for my mixer...
my RF freq is 2.447G and LO is of 2.448G.

thanks....

Andrew,
i read that pdf.
but it was not clear to me how to choose second harmonic for my frequencies.
LO = 2.448GHz and RF = 2.447GHz.

thank you..
