3 Tactics for Configuring Phase-Coherent RF Signal Generation

White Papers


As the number of higher throughput applications grows, there is a need for wider bandwidth and network coverage in wireless systems. However, given limited spectrum allocation, you must look for ways to improve spectral efficiency and signal-to-noise ratio (SNR). Multi-antenna techniques, such as multi-input multi-output (MIMO), and beamforming can help you achieve diversity, multiplexing, and antenna gain in order to improve spectral efficiency and SNR.

This white paper will help you understand phase coherence and why it matters, and offer tactics for generating phase-coherent signals.

Testing multi-antenna systems requires a test system capable of providing multiple signals and a constant phase relationship between the signals. Employing different tactics for configuring phase-coherent signal generation leads to different measurement results.
