In-Design Thermal Analysis For MMIC And RF PCB Power Applications


Next-generation wireless communication and radar systems often demand increased RF power within a smaller footprint to meet the performance and size requirements of their respective commercial and aerospace applications. As a result, RF front-end electronics are exposed to the risk of higher operating temperatures, which degrade RF performance and threaten device reliability. For many device ma... » read more

Radar For Automotive: How Far Can A Radar See?


In the previous entries of this blog dedicated to automotive radar, the reason for using radar and the principle of operation of the frequency modulated continuous wave radar were presented. Now, we will focus on the performance of the system, starting with its maximum detection range: how far can we detect an obstacle ahead? We need to have as much foresight as possible, to be able to detect a... » read more

GaN 8Gbps High-Speed Relay MMIC For Automated Test Equipment


An 8 Gbps high-speed relay MMIC for an Automated Test Equipment (ATE) using a gallium nitride is developed and evaluated. Metal-Insulator-Semiconductor structure with a tantalum oxynitride is employed to reduce a leakage current for ATE applications. The fabricated MMIC shows 0.3 nA of the leakage current, 12 GHz of a -3 dB bandwidth, and excellent eye-opening of 8 Gbps signals with a 18-lead... » read more

EDA Software Design Flow Considerations For The RF/Microwave Module Designer


Miniaturization of consumer products, aerospace and defense systems, medical devices, and LED arrays has spawned the development of a technology known as the multi-chip module (MCM), which combines multiple integrated circuits (ICs), semiconductor die, and other discrete components within a unifying substrate for use as a single component. This white paper outlines the steps for implementing an... » read more

RF To mmWave Design For Systems


RF-enabled next-generation communication systems and connected devices are differentiated by their performance, size, and cost. Traditionally, custom proprietary IC designs, leveraging the latest advanced-node technology, were developed to meet these product requirements. Increasingly these challenges are being met by moving beyond single IC solutions. Today’s electronic systems often integra... » read more

RF/Microwave EDA Software Design Flow Considerations For PA MMIC Design


In this white paper, a gallium arsenide (GaAs) pseudomorphic high-electron mobility transistor (pHEMT) power amplifier (PA) design approach is examined from a systems perspective. It highlights the design flow and its essential features for most PA design projects by illustrating a simple Class A GaAs pHEMT monolithic microwave IC (MMIC) PA design using Cadence AWR Microwave Office circuit desi... » read more

Rising Fortunes For ICs In Health Care


Semiconductors are increasingly finding their way into a variety of medical devices, after years of slow growth and largely consumer electronics types of applications. Nearly every major chipmaker has a toehold in health care these days, and many are starting to look beyond wearable such as the Apple Watch to devices that can be relied on for accuracy and reliability. Unlike in the past, the... » read more

Overcoming Next-Generation AESA Radar Design Challenges


Phased array antennas were first used in military radar systems to scan the radar beam quickly across the sky to detect planes and missiles. These systems are becoming popular for a variety of applications and new active electronically scanned arrays (AESAs) are being used for radar systems in satellites and unmanned aerial vehicles. As these systems are deployed in new and novel ways, size and... » read more

Manufacturing Bits: Feb. 6


GaN trusted foundry HRL Laboratories--an R&D venture between Boeing and General Motors--has launched a new foundry service for use in advanced millimeter-wave (mmWave) gallium-nitride (GaN) technology applications. HRL’s process, called T3-GaN, is a high-electron-mobility transistor technology. It will enable the fabrication of GaN-based monolithic microwave integrated circuits (MMICs... » read more
