Ted Rappaport, founding director of NYU WIRELESS and a leading proponent of using the millimeter wave spectrum for wireless communications, discusses the FCC's recent rulemaking actions and technology developments that are paving the way to 5G.
Pasternack unveils a new family of instrumentation grade directional waveguide couplers boasting accurate performance up to 110 GHz. These ultra-high frequency waveguide couplers are commonly used for signal sampling and other general applications in wireless transmit/receive systems, test benches, satcom, radar systems, point-to-point backhaul and telecom.
Microwave Development Laboratories Inc. will offer a sampling of its extensive expertise and product lines based on high-performance waveguide technology at the upcoming 2015 IEEE International Microwave Symposium and exhibition scheduled for May 17-22, 2015 in Phoenix, Ariz.
SPINNER's EasySnake combines the flexibility of a conventional RF test cable with the excellent low-loss trans mission characteristics of a classic waveguide system, initially for the frequency range from 75 to 110 GHz. The EasySnake retains its form and orientation in the measurement setup and therefore does not require additional supports or cable clamps.
A.T. Wall Company, a world-class supplier of superior precision tubing and fabricated metal components, announces its new standard waveguide stocking program. Through this new program, all standard waveguide sizes will be shipped within five days from stock, while all other special waveguide sizes will be made to order.
Vubiq Networks in Irvine, CA is proud to announce a fully integrated 60GHz radio transmitter module. Small and lightweight, the unit features a patented chip to waveguide transition that is compatible with WR-15 and UG-385/U waveguide flange interfaces.
TEGAM Inc., a leading supplier of innovative RF power measurements, was recently awarded Patent No. 8,610,069, “Coaxial to Dual Co-Planar Waveguide Launcher for Microwave Bolometry,” This patent describes a new way to construct bolometers—a type of microwave power sensor that uses thermistors—that makes them more accurate and easier to assembly.
Spacek Labs model FSP94-2 is a narrow (2 percent bandwidth) bandpass filter from its new line of FSP Series waveguide filters. Designed in WR-10 waveguide, the FSP94-2 has a passband of 2 GHz centered at 94 GHz. The lower and upper 20 dB reject points are 92 and 96 GHz respectively.
It is always a concern at high millimeter wave band that there is not enough power to drive the mixer, especially full waveguide band. Model FDB-XX-E1 series externally biased, balanced mixers is especially developed for this purpose. The mixers are offered in four waveguide bands to cover frequency spectra from 50 to 140 GHz. These mixers employ high performance GaAs Schottky beamlead diodes and balanced configuration to produce superior performance with a very low LO pumping level.
A1 Microwave has released the world’s smallest waveguide X-Band Tx and Rx filters for military satcom applications. The filters have less than 0.3 dB insertion loss and have greater than 90 dB rejection in the complementary frequency bands. They are considerably shorter and lighter weight than equivalent filters on the market, which makes them ideal for portable solutions. These are stock items for immediate delivery.
