The array is composed of four elements which each have two patches and a parasitic element. The parasitic element aids in producing a wider beam in one dimension to give better coverage. The beams may be steered by varying the phase shift between elements to provide near hemispherical coverage.
With the next big step in mobile communication, 5G will introduce new RF techniques, new frequencies and signal bandwidths. Ultimately, 5G New Radio (5G NR) will bring higher speed, reduced latency, more capacity and improved reliability. While the system parameters will change, the hardware to enable the new major step in mobile technology towards 5G NR will be different as well. New technologies will be deployed and designs have to follow the new requirements.
This article discusses how a real-world filter’s deviation from ideal behavior needs to be quantified and that shape factor and selectivity are tools to use in this process. It touches on how both resonator Q and the filter order (number of resonators in a design) can influence a filters behavior in the transition band.
Qorvo offers a variety of antenna-plexer solutions designed for enabling complex antenna sharing. Antenna-plexers reduce the number of antennas required, creating space for smaller bezels and larger edge-to-edge screens.
Wireless infrastructure incorporates differing radio frequency and fiber optics technologies. HUBER+SUHNER manages both technologies and offers the appropriate solutions for each macro cell application. HUBER+SUHNER also provides expertise in radio frequency, fiber optics, and low frequency.
