Design Enablement for RF and Microwave IC Design: Part II

This two-part series from Jazz Semiconductor presents recent developments in design-support methodology from a pure-play wafer foundry specializing in RFCMOS and advanced CMOS technologies, including BiCMOS, SiGe BiCMOS and high voltage CMOS. In this s...
Variations in semiconductor manufacturing technology are unavoidable; therefore, the IC must be designed for yield even at the extremes of process variation. The goal of statistical and corner models is accurate simulation of the process-induced variation of circuit performances, such as gain-bandwidth products, distortion levels and phase noise. Process...

Gallium Nitride Microwave Transistor Technology for Radar Applications

This article reviews the relative merits of silicon (Si), gallium arsenide (GaAs), silicon carbide (SiC) and gallium nitride (GaN) materials and describes how the attributes of each impact the operation of microwave transistors for the generation of hi...
Many microwave radar transmitters require active devices that can produce RF output power in the order of kilowatts to even megawatts. Routinely, microwave traveling-wave tube devices are utilized for this application. However, the currently used traveling-wave tubes are inefficient, large, expensive and have suspect reliability. While semiconductor-based amplifiers in...

A Dual-mode Sensor Solution for Safe Helicopter Landing and Flight Assistance

Helicopters are in danger of suffering damage, collision or crashes when taking off and landing in brown-out/white-out conditions. This article provides an overview of how new developments in radar and laser technology and particularly sensor fusion ca...
During take off and landing flight phases, helicopters can encounter serious brown-out or white-out problems in dusty, sandy or snowy areas as the downwash of the rotor blades creates dust clouds that can completely engulf the helicopter. This is graphically illustrated in Figure 1 . During landing in particular,...
