RF Modulator vs Frequency Converter: Key Differences, EVM Impact, LO Leakage and I/Q Imbalance Correction

Are you seeing poor EVM in your satellite upconverter system? The cause might be an overlooked detail in your modulator’s architecture, which is hurting your signal quality and system performance. The main difference is function. A frequency converter simply shifts a signal’s carrier frequency. An RF modulator, like a quadrature modulator, also impresses a baseband […]
