Characterizing Active Phased Array Antennas

Designing and implementing an active phased array antenna requires precise characterization of individual components and the integrated performance of the array. To ensure an accurate test of the intended adaptive nature of the active phased array antenna, the embedded algorithms need to be tested as well. This application note aims to explain test procedures and… Read more »

Millimeter-Wave Beamforming: Antenna Arrays & Characterization

Millimeter-wave bands are of increasing interest for the satellite industry and under discussion as potential 5G bands. Antennas for 5G applications make use of the shorter element sizes at these high frequencies to incorporate a larger count of radiating elements. These antenna arrays are essential for beamforming operations that play an important part in next… Read more »

Estimation of DoA Based on Large-scale Virtual Array Data

Future 5G communication systems operating in the mmwave bands (6-100 GHz) will rely on multi-antenna techniques like beamforming and MIMO 1. Therefore, measurement and description of spatial channel information (direction of arrival DoA, direction of departure DoD) is of high relevance for mm-wave system design and channel modeling.
Application Notes:

mm-Wave Band Signal Generation and Analysis

This application note describes how to generate and analyze wideband digitally modulated signals in the mm-wave range. Measurement results such as error vector magnitude (EVM) and adjacent channel power (ACLR) are shown. Two test setups and their measurement results on a commercial V-band transceiver module are presented
