Mixer & frequency converter testing

Mixer & frequency converter testing

Mixer performance verification

Mixers are a fundamental element in a wide range of applications such as modulators, phase detectors, frequency converters and synthesizers in many RF and microwave systems. They are a standard building block in wireless communications systems and radar systems. In many cases, the mixer is an important part that determines the overall system performance. Rohde & Schwarz test solutions give you deep insights into the performance of your device and allow you to effectively validate your design.
