What problem does it solve?

This Skill helps you analyze unwanted mixer spurious products and intermodulation so you can predict and validate RF/IF frequency behavior without guessing.

Core Features & Use Cases

• Intermodulation table (IMT) modeling with mixerIMT: Define and tune an MxN spur model using the mixerIMT object, including desired and suppressed products.
• Spur visualization for specific RF inputs: Generate spur charts at a chosen fRF using rfplot(m, fRF) to identify which products matter at that frequency.
• RF budget and cascade integration with spur-aware mixers: Combine mixerIMT with rfbudget to evaluate system gain, output frequency (IF), and noise figure in architectures where spurs matter.
• OpenIF-based frequency planning: Use mixerIMT concepts alongside OpenIF to find spur-free IF bands across multiband receiver/transmitter designs.

Quick Start

Create a mixerIMT with ConverterType set to Down, assign a custom 5x5 IMT with your desired and spur levels, and plot the spur chart at fRF=2.4e9.
