Radio-Astronomy LNA Boasts Noise Figure Under 0.2 dB
THE SQUARE KILOMETER ARRAY (SKA) radio synthesis telescope is estimated to require millions of receivers. To keep receiver cost down, CMOS technology is being looked at as an option. With recent improvements in CMOS transistors, this technology ...
Simulation And Measurements Prove RF-Relay Performance
TODAY'S MANUFACTURERS ARE being pressured to put their parts through more rigorous high-speed/ high-frequency testing. Teledyne Relays (www. teledynerelays.com), for example, recently collaborated with two customers to evaluate the performance ...
Imaging Systems Overcome Atmosphere And Materials
BOTH HOMELAND SECURITY and military agencies have been seeking technologies that detect guns, knives and improvised explosive devices (IEDs). Using the millimeter and sub-millimeter wavebands, techniques to image people when they are close to a ...
CST Acquires Flomerics' EM Business Line
For software vendors, acquisitions usually offer a chance to enter new market areas and an immediate way to provide new services and products for customers. Through its acquisition of Flomerics' (www.flomerics.com) electromagnetic (EM) simulation ...
Millimeter-Wave Power Divider Spans 10 To 45 GHz
THE MILLIMETER-WAVE ARENA continues to experience growth in applications like radar, microwave communications, and broadband test equipment. Finding a niche in such applications is the 4428C-2 two-way RF power divider, which boasts a ...
Reflector System Could Satisfy Antennas On Spinning Platforms
Current spacecraft antenna design must confront the problem of how to mount and deploy large reflector antennas on spinning platforms. The reflector spins at approximately 10 to 40 rpm to cover the desired scanned area on Earth. One solution - ...
MMIC Receiver Covers 4.5 To 10.5 GHz
A fully integrated gallium-arsenide (GaAs), monolithic-microwave-integrated- circuit (MMIC) receiver has been spawned for wirelesscommunications applications like millimeter-wave point-to-point radio, local multipoint distribution services ...
Luneberg Lens Offers Wide Scan With Multiple Pencil Beams
Recently, there has been a resurgence in research interest in spherical Luneberg and homogeneous lens antennas for launching multiple pencil beams. With these approaches, all of the generated beams are almost identical because of the inherent ...
Digital Phosphor Oscilloscopes Tackle Video Measurements
Video measurements pose a tough challenge because of the complexity of video waveforms. Such waveforms often combine the signals that represent the video picture with the timing information that is needed to display the picture. Although some ...
2.4- And 5-GHz Pas Form IEEE 802.11n Building Blocks
With the growing popularity of Wi-Fi, IEEE 802.11n wireless-localarea- networking (WLAN) capability is being designed into many next-generation products. To simplify this process, two new power amplifiers (PAs) promise to simplify design ...
Broadband Access Will Mix Wireless With Wire-Line Technologies
By 2015, five billion people will be "connected" - with the majority of them always on and enjoying broadband access. This estimate comes from Nokia Siemens Networks (Espoo, Finland). The company expects those broadband customers to be served ...
