Overview

The TW7972 is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision is a top priority. The antenna provides superior multi-path rejection and axial ratio, a linear phase response, and tight Phase Centre Variation while protecting against intermodulation and saturation caused by high level cellular 700MHz signals. The TW7972 is designed with a dual feed circular stacked patch element. The two signals from the orthogonal feeds are summed in quadrature, pre-filtered in a low loss filter to protect against interfering signals, amplified in high linearity, wide-band LNA, then band-split, tightly filtered and amplified prior to signal recombination at the output.
