    Designing With Plastic RF Power Transistors

    For many semiconductor products, plastic long ago emerged as the package technology of choice. For commodity products, such as small signal transistors, plastic offers low-cost encapsulation that is easily scaled to high volumes. For RF power amplifiers, plastic packaging helps address certain performance limitations inherent in ceramic devices. This white paper outlines the six main benefits of RF power plastic packages and provides recommendations on PCB layout. It also discusses mounting and soldering techniques that help create a robust, cost-effective design solution using over-molded plastic RF power devices.

Leveraging Advanced Satcom Modems for Extreme Environmental Challenges

Case study on how a telecommunications and information services company used advanced Satcom modems to overcome extreme environmental challenges.

Alleviating RF Transmit Signal Corruption in Wireless Data Systems

High speed wireless data systems can often experience RF transmit signal corruption that limites the power level a wireless data device can put out at its antenna. To achieve the best possible range coverage area, one needs to maximize RF transmit power. However, this can cause spectral regrowth once the integrated LNA is activated.

Introduction to FDTD EM Simulation for Automotive Radar

Electromagnetic simulation has been used by RF engineers for many years to aid the design of automotive radar sensors, but the increasing demands of advanced driver assistance systems (ADAS) are changing the methods used.  Accurate modeling of increasingly complex circuits and antenna systems leads to simulation problem sizes too large (in terms of physical memory – RAM) for traditional frequency-domain finite element method (FEM) formulations.  As a result of those limitations, design engineers who use FEM tools are forced to simplify their simulation models to fit the computational resources available, trading away accuracy and limiting the effectiveness of their simulator.

    4 Electronic Design Requirements Of The System-Integrated Soldier

    Perhaps most famously portrayed in Robert Heinlein’s Starship Troopers (1959), the idea of the “future soldier” has been around for decades. As rehashed in countless science fiction films and video games, the stereotypical future soldier is equipped with a protective exoskeleton, enhanced sensory equipment, seamless communication systems, and advanced weaponry. While the concept once seemed implausible, there are many real-world projects under way focused on realizing those seemingly fictitious warfighter capabilities — by integrating a plethora of diverse electronic subsystems into a cohesively operational suit.

    7 Noteworthy Technologies From IMS2014

    At the 2014 IEEE MTT International Microwave Symposium earlier this month, I had the opportunity to speak with the event’s general chair, Dr. Larry Dunleavy, about the state of the RF and microwave design industry. While he acknowledged that it is a time of relative uncertainty — due in large part to constrained military budgets and conservative fiscal forecasts for 2014 — he also pointed out that there are plenty of emerging markets where RF and microwave technology is making a significant impact. With the Internet of Things (IoT) driving innovation in burgeoning markets like automotive and healthcare  and the development of 5G pushing wireless technology to further heights, there was good reason for nearly 600 companies to flock to the IMS2014 exhibition in Tampa, Fla.
