In the past few years, the interest in the millimeter-wave spectrum at 30 to 300 GHz has drastically increased. The emergence of low cost high performance CMOS technology and low loss, low cost organic packaging material has opened a new perspective for system designers and service providers because it...

The development of multiple beams and reconfigurable antennas has always been tightly connected to that of beam-forming networks. The beam-forming network (BFN) is often the dominant component, the true “heart” of most multiple beams antennas. Beam-forming networks are complex networks used to precisely control the phase and amplitude of...

To address the space, cost and power-consumption constraints of mobile portable devices from cell phones to PDAs and laptops, the trend in RFIC design is to combine the analog baseband (BB) and processor interface into a single chip solution (see Figure 1 ). With new products experiencing narrow market-windows...

Frequency converters, a key component in modern satellite communications systems, create special characterization challenges for developers and manufacturers. The signals, processed by these converters and their modulation formats, can change dramatically from day-to-day and even hour-to-hour. The channels may be re-allocated to different services, and with its high cost,...

Growing demand for higher communication bandwidths has led to considerable development of systems operating at millimeter-wave frequencies. These systems have, in turn, stimulated research and development efforts of 26 to 40 GHz components such as TWT and solid-state amplifiers and phase shifters. These novel components often suffer from bandwidth...

There is an increasing demand for wireless commercial applications operating at millimeter-wave frequencies. The emergence of millimeter-wave wireless applications such as LMDS, WLAN and automotive anti-collision radar has brought new requirements on device technology and the systems used to characterize these devices at higher frequencies. Many researchers specifically require...

In modern “on the move” military communications there is an increasing emphasis on performance in adverse conditions requiring compact, efficient and ruggedized packaging with a cost-effective price tag. With this philosophy in mind, Locus Microwave Inc. introduces the UB61000 series medium power X-band Block Up-converter (BUC) featuring an L-band...

Products include: programmable attenuators, variable step attenuators, terminations, loads, DC blocks, bias tees and RF detectors. In addition, the catalog...

Autonomous Software-defined Radio Receivers for Deep Space Applications Jon Hamkins and Martin K. Simon, Eds. John Wiley & Sons Inc. • 457 pages; $150 ISBN: 978-0-470-08212-6 The purpose of this book is the development of techniques to autonomously configure an all-digital software-defined radio (SDR) receiver for whatever type of...

Millimeter-wave Receivers These custom-designed millimeter-wave receiver modules are designed for radiometer applications. Two downconverter models have been custom-designed to operate at K-band (20 to 40 GHz) and V-band (50 to 75 GHz). Gain calibration is accomplished using an internal K- or V-band noise source, a noise injection coupler and...
