The Model 500S1G6 from AR is a solid-state broadband amplifier that operates over the 0.7 to 6 GHz frequency range, and is designed for applications where instantaneous bandwidth, high gain, and linearity are required. The low level of spurious signals and linearity of this device makes the 500S1G6 ideal for use as a driver amplifier in testing wireless and communication components and subsystems, and EMC testing applications.
Low-profile, concealed antennas are often desired for diverse applications across many military and commercial vehicle platforms. Since antennas mounted close to the ground have decreased efficiency, potential antenna applications need to benefit from the coupling to the ground and/or rely on short distance communication. Traditional analytical propagation models are not applicable to short-distance near-ground signal propagation, so numerical modeling is required. FEKO electromagnetic simulation technology is an attractive solution with superior effect capabilities that account for mutual coupling between receiving and transmitting antennas.
The Murchison Widefield Array (MWA) radio telescope was constructed as a precursor to the Square Kilometer Array (SKA) at the Murchison Radio-astronomy Observatory in Western Australia. This case study focuses on this electronically steered phased array, where steering is achieved by introducing phase delays to each element in the array. The primary beam patterns in phased array antennas must be accurately known in order to correctly calibrate and image the data collected by the radio telescope.
There are many key parameters that must be considered for RF inductor selection, including the mounting type, inductance value, current rating, DC resistance, self-resonant frequency, Q factor, and temperature rating. A balance must be met between the desired smaller sizes of the inductor package, and the inductance value and current rating. Once these two parameters are determined, the other parameters can then be optimized.
Flexible hybrid electronics (FHE) is a category of microelectronics using novel materials with stretchable, conformable, and flexible form factors. FHE enables wearables, medical Internet of Things (IoT) applications, defense applications, and more by shifting from electronics based on rigid and fragile circuit boards to flexible electronics components mounted on substrates, such as plastics and textiles.
The millimeter wave frequencies being planned for 5G systems pose challenges for channel modeling. At these frequencies, surface roughness impacts wave propagation, causing scatter in non-specular directions that can have a large effect on received signal strength and polarization. To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. This example uses Wireless InSite’s diffuse scattering capability to perform simulations of an indoor wireless network.
The Fischer Plastic Series is a family of high performance, fully insulated plastic connector bodies that are all compatible with Fischer’s metallic connectors.

This short animation shows predicted RCS from an air traffic control radar with an aircraft flying over a wind farm, before and after the static ground clutter (returns from terrain) are filtered out. A basic filter has then been applied to remove the portions of returns with 0-Doppler (static clutter from the ground and wind turbine towers) to approximate what a radar might see after attempting to filter out objects not in motion. Although actual radars have much more sophisticated signal processing, this basic before/after animation of RCS from subsequent scans shows the problem that standard Doppler filtering would encounter when processing returns from a wind farm.
In this video, a Remcom engineer walks through the steps to set up and tune a Ku Band microstrip lens in Rotman Lens Designer (RLD). We populate the physical, electrical, and transmission line properties and analyze the performance of the lens by plotting the array factor and beam to array phase error. This data helps us to further tune the lens by adjusting the focal ratio and beam port excitation, and then we export the S-Parameters. Finally, we discuss the various options for exporting the file and importing into XFdtd EM Simulation Software, including the use of a customized script. The script import method automatically sets up the ports and also includes the material properties.
