Configuring Phase-Coherent RF Measurement Systems

Ever since the first radio waves were transmitted, engineers have continually sought new ways to use electromagnetic microwave signals. While RF signals have been incorporated in a wide variety of applications, two specific applications that use one common technology are wireless communications and Radio Detection and Ranging (RADAR). In essence, both applications are unique in that they use the spatial dimension of electromagnetic waves. Today, many wireless communications systems incorporate multiple input, multiple output (MIMO) antenna schemes to take advantage of the multipath signal propagation. In addition, many of today’s modern RADAR systems use electromagnetic beam steering as replacement for the traditionally mechanically steered transmit signal.

These applications and others are some of the primary drivers behind the demand for multichannel phase-coherent RF measurement systems.
