The last decade has been marked by rapid development in the avionics integrated systems that have important advantages: Fewer units, smaller size, less weight, lower power use, reduced cable count, extensive built-in test equipment (BITE) and integrated maintenance features. This article describes different aspects of RF design of the...

Modern wireless communication systems demand not only high efficient RF and microwave amplifiers, but wideband designs too. Switchmode power amplification classes can provide both benefits simultaneously, but theoretical knowledge must be combined with important practical considerations to get these advantages. There are important practical considerations that limit the theoretical...

This paper describes a concept of non-adaptive Digital Feed-forward Linearization. A feed-forward amplifier is a system designed to reduce the spectrum re-grows appearing due to the amplifier’s nonlinearity. There are several general techniques to reduce nonlinearity effects. They are divided into two major groups. One of them (called “predistortion”)...

Phase noise is the most important figure of merit of microwave oscillators. 1,2 Although a number of publications have addressed this phenomenon, it still remains one of the most challenging aspects in oscillator design. This article briefly summarizes the research and development effort in the area of low-noise signal...

Many demanding applications in the RF and microwave industry require fixed frequency ultra low phase noise frequency sources that provide a high level of performance and reliability. These low noise frequency sources are often comprised of individual quartz-based ovenized crystal oscillators (OCXO) coupled with modular system building blocks such...

Circuit weight and density are critical factors in some microwave applications, notably in satellites and airborne systems, including unmanned aerial vehicles (UAV). To meet the needs for high electrical performance with mechanical reliability, Rogers Corp. has developed a new addition to its well-known line of RT/duroid® circuit-board materials: RT/duroid...

Two new UHF TV amplifiers, one designed specifically for digital service, the other designed for analog service, both with the highest power density currently available, are now offered from Power Module Technology (PMT). The advanced technology incorporated into these amplifiers is also available for microwave applications such as radar,...
