Patent ID: 7016823

Claim:
A method for operating a data processing system to simulate a mixer having a known design, said mixer having an RF port, a LO port, and an IF port, said method comprising generating an estimate, b 2 , of the output signal leaving said IF port when an input signals a 1 , a 2 , and a 3 are applied to said RF port, said IF port, and said LO port, respectively wherein, b 2 = f ( a 1 , a 3 )+ S 22* a 2 where: S22 is a constant and, f ⁡ ( a1 , a3 ) = ∑ i = o M ⁢ ∑ j = o N ⁢ C ij * a1 i * a3 j said coefficients C ij being contants that depend on said mixer design and wherein M and N are integers greater than 0.
