Abstract
A mixer harmonics calculator system is described. The system is designed to perform rapid online calculation of mixer harmonics up to 10×10 RF and LO order using actual measured parametric data optionally supplemented with interpolated or otherwise calculated data. Output options from the mixer harmonics calculator include a comprehensive range of presentations of tabular and graphed data. The mixer harmonics calculator is designed to function either independently or within a more comprehensive electronic component database search system.
