Tackling Millimeter-Wave Signal Analysis Challenges
White Papers
Millimeter-wave technology transforms wireless communications. Next-generation 5G, satellite, and automotive radar communications achieve higher data throughput and super-fine range resolution using ultra-wide bandwidth. Millimeter-wave technology is a key enabler and provides ample margin for performance improvement, but it creates challenges such as path loss, tight design margins, complex modulation, and stringent standards.
At millimeter-wave frequencies, excessive path loss makes radio-frequency (RF) power limited and costly. Also, measuring performance metrics using over-the-air (OTA) test methods makes achieving accurate and repeatable results more difficult. Wide bandwidths enable high-throughput data, range resolution and accuracy, and low latency but also introduce more noise. The excessive path loss and noise increase test complexity and measurement uncertainties.
