EM-Plugs: Speedy Simulation for Higher-Accuracy RF Digital Twins (Download)
RF ICs are widely deployed across advanced applications such as 5G millimeter-wave (mmWave) systems, satellite communications, automotive radar, and high-end test and measurement platforms. Devices such as low-noise amplifiers (LNAs), power amplifiers (PAs), RF switches, digital step attenuators (DSAs), digitally tunable filters, and beamformers address these applications with solutions operating up to 90 GHz.
When an RF IC is implemented on a substrate that differs from the vendor’s reference design, RF performance can deviate significantly, especially as the frequency ascends. Predicting this behavior isn’t straightforward, and traditional S-parameters can’t account for these variations.
