What are the driving forces behind today’s rapidly changing RF semiconductor landscape? This article delves into the two major driving factors of change in the industry: the desire for ubiquitous sensing and the demand for more and better connectivity.
Series-fed patch elements forming an array are simulated to demonstrate antenna performance and beamforming including S-parameters, gain, and effective isotropic radiated power (EIRP) at 28 GHz. Beam steering is performed in one plane by adjusting the phasing at the input ports to each of eight elements.
An 8x8 planar antenna array creates narrow beams capable of scanning large sectors in front of the antenna. This example focuses on displaying typical simulation results for beams and possible plots of coverage from the full array and combinations of sub-arrays.
This article presents a solution of using four L60T01 amplifiers in hybrid configuration as an alternative for a higher output power amplifier.
This white paper presents and discusses the advantages of using high power RF amplifiers that employ a high voltage GaN technology operating above the industry standard of 50 V.
It is recommended to use jitter measurement instruments for both the time and frequency domain in order to differentiate between fast and slow moving artifacts. This white paper compares measurement results of jitter in the time and frequency domain.
This white paper presents a technique using quartz crystals mated with energy saving low power SoCs for reducing oscillator power consumption while achieving optimal oscillation margin. The paper also demonstrates measurements and key principles for designing reliable and low power oscillators.
The range for spectrum mask measurements has traditionally been in the MHz range, but mmWave signals require new regulations and test protocols in the 30 to 300 GHz range. This paper discusses the special considerations for spectrum emission mask measurements for mmWave frequencies.
This article examines the design challenges for practical millimeter-wave power amplifiers delivering the necessary power, linearity, and efficiency for future 5G networks.
Multi-mode cavity filters offer high power handling and good performance as a compact device. Such filters are complex and sensitive to changes in the structure, meaning that their design can be time-consuming or even impossible with conventional methods. This article shows how the CST® filter synthesis tool Filter Designer 3D, part of the simulation software CST STUDIO SUITE®, can be used to design and tune a multi-mode compact ridged waveguide filter to meet stringent specifications.
