Dear Sridhar:

The PCB losses depend on several factors including frequency, substrate
loss tangent, relative dielectric constant, and trace geometries.

The mathematical formulae governing PCB conductor and dielectric losses
readily available in SI literature.

An insightful approach for anlaysing/minmizing loss is to apply software
such as
Mathcad, Matlab, HSPICE, HyperLynx, etc.

I particularly like HyperLynx for loss analyses because of the
flexibility and
efficiency it offers.

Kind Regards,

Abe Riazi
