Improve Testing at mmWave (Millimeter Wave) Frequencies

The wide bandwidth requirements of next generation wireless systems such as 5G cellular communications, military and automotive radar, and IEEE 802.11ad and 802.11ay are driving the move to millimeter wave bands, where more contiguous spectrum is readily available.

Testing at millimeter wave (mmWave) frequencies can be more difficult even than you anticipate, and many things you could ignore at lower frequencies have a much larger impact at mmWave. This makes your measurement accuracy and repeatability even more critical. For example, millimeter wavelengths are extremely sensitive to cable and connector errors, so learning how to make multiple measurements per connection can help remove uncertainty from measurements.

Keysight’s experience with mmWave technology can help you understand the key pitfalls to watch for, test setup modifications you may want to consider, and what factors will most impact your measurements in the mmWave frequency range.
