Abstract
A recently proposed approach for the
prediction of power amplifier (PA) intermodulation
distortion (IMD) on the basis of single-tone Harmonic
Balance simulations is used in this paper for the definition
of a numerically efficient design procedure of highly linear
microwave power amplifiers. In particular, it is shown how
standard design goals on third or fifth order
intermodulation products, usually involving timeconsuming
two-tone HB analyses, are more simply but with
sufficient accuracy taken into account by means of faster
single-tone HB analyses in the iterative design process. The
proposed procedure is compared with standard approaches
in the design case of single-transistor and multiple
paralleled-transistors MMIC amplifiers, showing dramatic
reductions in computation time.
