As the world’s market continues to grow exponentially in the need for in wireless connectivity in mobile devices and data networks, manufacturers are struggling to keep up with the production of spectrum bands that are required to carry the data. This demand results in the requirement of more RF components for connected devices, which simultaneously adds more cost and power demands, and forces manufacturers to continuously add new models to keep up with bandwidth needs. This pressures the carrier aggregation and more complex MIMO designs to have dramatically smaller and cheaper RF filters. This white paper offers an in-depth discussion on the new Infinite Synthesized Networks (ISNTM), a new filter design solution that can be used to develop a state-of-the-art Band 3 duplexers using low-cost SAW fabrication, while achieving high performance results.
When using bundles of electrical cables in vehicles, aircrafts, ships, and buildings, electrical designers are met with the challenges of electromagnetic compatibility and interference. The long cables are more prone to radiate or pick up irradiation than many other electrical components and systems. This white paper discusses how these challenges may be met through the aid of FEKO’s electromagnetic simulation capabilities.
A transistor was tested in a UHF pulsed radar power amplifier operating with GaN technology in order to achieve a higher voltage output. This article investigates the relationship between Fe concentration in the buffer layer and breakdown voltage of an AlGaN/GaN on SiC HEMT transistor in order to operate in a UHF power amplifier operated at a bias of 100V or higher.
Solid state amplifiers have the benefit of potentially higher efficiency, smaller size, and lower weight, which translates to lower costs in launching spacecrafts into orbit. Another advantage of solid-state power amplifiers is the much lower than kilo-volt range of operating voltages, which simplifies the design of the power supply subsystem. There are also significant advantages in using GaN HEMT technology for achieving higher frequency bandwidth, high voltage operation, and radiation hardness for high reliability space applications. The high efficiency of a radar front-end power amplifier becomes a key element of a spacecraft mission design with a limited prime power budget. As a result, amplifiers and transistors for spaceborne applications are adopting GaN technology to achieve higher efficiency in yielding GaN radar transistors. This white paper presents and discusses the RF burn-in analysis of 100V P-band aerospace GaN radar transistors, with complete results, and junction temperature modeling.
In order to better understand the earth’s global carbon cycle, NASA and ESA have implemented programs with the objective to make scientific measurements of the earth’s biomass. NASA uses an airborne synthetic-aperture radar (SAR) system operating in L-band, while ESA uses a GaN based system. This white paper presents a 2-stage, 40 dB gain, 1 kilowatt transmitter pallet as an alternative solution for ground-penetrating SAR applications in P-band
MtronPTI recently released a line of broadband, solid-state, power amplifiers covering the 6 to 18 GHz range with up to 40 Watts power serving the needs of tactical communications, satellite terminals, electronic warfare, radar, point-to-point backhaul, medical, industrial, and scientific applications.
EMI Filters are used to prevent electromagnetic interference in avionics and aircraft systems, as well as military shipboard/vehicle electronics, and in military communication systems. Electromagnetic interference can cause a complete loss of data in communications systems, or a simple decline in data quality.
