Mixer Calculator Help & Theory
Overview
▼
The Mixer Calculator is a tool for analyzing spurious products in frequency mixers. It supports both up-conversion and down-conversion operations, various mixer types (unbalanced, single-balanced, double-balanced), and multiple modeling approaches for amplitude prediction.
Key features include:
- Comprehensive spurious product analysis
- Multiple mixer model types (Henderson, Harmonic Balance, Linear)
- Visual spectrum display with in-band/out-of-band indication
- Spur matrix visualization
- Configurable IF filter parameters
- Performance metric calculations (IP3, P1dB, NF)
