Upconverting Modulated Signals to Microwave with an External Mixer and the R&S®SMF100A Microwave Signal Generator Application Note

2022-03-30
Vector modulation is becoming more and more widespread in microwave and satellite communications applications. Direct generation of digital modulation at microwave frequencies is, however, expensive and difficult to implement. An alternative to generating I/Q-modulated signals in the microwave range is frequency upconversion of usual (low-frequency) vector signals. This Application Note describes the principle of upconversion using an external mixer. The basics of mixer operation are introduced and the conversion process is demonstrated in detail with a test setup and corresponding measurements. The mixer selection guide will make it easier to choose a proper mixer for individual applications.
