    Due to the enormous advances made in semiconductor technology over the last few years, high integration densities with moderate costs are achievable even in the millimeter-wave (mm-wave) range and beyond, which encourage the development of imaging systems with a high number of channels. The mm-wave range lies between 30 and 300 GHz, with corresponding wavelengths between 10 and 1 mm. While imaging objects with signals of a few millimeters in wavelength, many optically opaque objects appear transparent, making mm-wave imaging attractive for a wide variety of commercial and scientific applications like nondestructive testing (NDT), material characterization, security scanning, and medical screening. The spatial resolution in lateral and range directions as well as the image dynamic range offered by an imaging system are considered the main measures of performance. With the availability of more channels combined with the powerful digital signal processing (DSP) capabilities of modern computers, the performance of mm-wave imaging systems is advancing rapidly.

    Gallium nitride (GaN) technology is transforming RF monolithic microwave integrated circuits (MMICs) for power amplifiers (PAs), switches, low noise amplifiers, and more. Vendors are now producing GaN MMICs in volume and achieving outstanding performance. GaNs characteristics enable PA MMICs with 35 times the output power of GaAs alternatives or much smaller die sizes from L-band through Ka-band. High-power switches with low insertion loss up through 18 GHz have been developed. Low-noise amplifiers have been demonstrated with noise figures equivalent to gallium arsenide (GaAs) but with much higher input power survivability. The market for GaN RF MMICs spans commercial and military applications, including base station, cable television infrastructure, communications, radar and electronic warfare (EW), among others.

    A 120-GHz-band 10-Gb/s wireless link using an InP-HEMT-based MMIC was introduced. This link is suitable for last-mile access of 10GbE, live-relay transmission for 4K cinema, and multiplexed HD videos. The transmitter and receiver MMICs were developed to extend the link distance while maintaining the capacity of 10 Gb/s. The 120-GHz wireless link using the MMICs successfully demonstrated wireless transmission of 10GbE over the link distance of over 5 km. We also designed QPSK modulator and demodulator MMICs to improve the spectral efficiency of the wireless link. Fabricated QPSK MMICs and modules performed 10-Gb/s transmission with the BER of 10-10 at the received power of -38.5 dBm. In the future, we hope to implement QPSK modules in the 120-GHz-band wireless link equipment. We would also like to advance the QPSK modulator and demodulator MMICs and modules to handle bit rates of up to 20 Gb/s. View full abstract»

    Wireless and semiconductor industries have recently discussed their vision of fully autonomous and seamless wireless connectivity by combining advanced nanoscale CMOS technologies with innovative hybrid-domain circuits and systems solutions. One goal inside this broad vision is to develop a smart mobile companion device with high performance, adaptive connectivity, and high power efficiency. High performance is the essential ingredient to coping with the ever-increasing add-on functionalities in small handheld devices, integrating cellular, WiFi, Bluetooth, Global Positioning System and mobile TV. All of these generate many opportunities for furthering the horizons of radio frequency integrated circuits (RFICs) in the years to come. View full abstract»

    Many countries will experience the effects of an aging population, resulting in a high demand of healthcare facilities. Development of novel biomedical technologies is an urgent necessity to improve diagnostic services for this demographic. Electrocar diogram (ECG) and temperature recording have been used for more than 50 years in medical diagnosis to understand various biological activities [1], [2]. A more recent development, electronic pill technology, requires the integration of more complex systems on the same platform when compared to conventional implantable systems. A small miniaturized electronic pill can reach areas such as the small intestine and can deliver real time video images wirelessly to an external console. Figure 1 shows an electronic pill system (i.e., wireless endoscopy) for a medical monitoring system. The device travels through the digestive system to collect image data and transfers the data to a nearby computer for display with a distance of one meter or more. A high resolution videobased capsule endoscope produces a large amount of data, which can then be delivered over a high-capacity wireless link. View full abstract»

  • A Software Framework for Automated Behavioral Modeling of Electronic Devices [Application Notes]

    Behavioral models such as macromodels, surrogate models, metamodels, and response surface models have many applications in diverse research domains such as aerodynamics [1], hydrology [2], mechanical engineering [3], and many more. When considering the design flow of electronic devices, these models are often used to characterize the time- or frequency- dependent behavior of an electronic component while taking all electromagnetic (EM) phenomena into account: crosstalk, attenuation, dispersion, and coupling effects for example [4]. Such models are of crucial importance for efficient design space exploration, design optimization, and sensitivity analysis [5], [6]. A key advantage is that they are calculated independently of the device's physics and that they are valid for over a wide range of design variables, taking into account multiple geometrical layout or substrate features. Additionally, the models can easily be linked together in a model cascade. View full abstract»

  • Latest Technology, Technological Challenges, and Market Trends for Frequency Generating and Timing Devices [Application Notes]

    The second and third generation of MEMS oscillators will target a larger market for compact oscillators in order to meet TCXO and OCXO performance requirements. While silicon-based timing devices are still not as capable as crystal oscillators of undertaking sophisticated tasks , they are getting better, and will eventually replace crystals in many contexts. That will produce further synergies for the industry as mass production becomes cheaper and easier. These days, designers require higher frequencies and low jitter in oscillators, while buyers demand low cost and quick delivery. Timely oscillator options that can deliver the highest desired performance, while minimally compensating design steps are the key to cost-effective solutions. Fortunately, in the ongoing battle to push the limits of technology and lower component costs, oscillator manufacturers continue to close the gap between highlevel performance and cost-effective purchasing, with conventional crystal technology paired with configurable oscillator technology. Like every exciting new technology targeting mass markets and driven by start-ups, confusion or exaggeration are present, but all in all, we believe that MEMS oscillators will follow the successful bulk acoustic wave devices as the second RF MEMS mass product.
