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.
Skyworks & RFMW introduces select digital attenuators. With up to 7-bits and 0.25 dB step accuracy, these select digital attenuators operate up to 4 GHz for both RF and IF applications. All attenuators are absorptive in 50 ohm environments and easily cascadable – impedance matching is not needed between attenuators.
With companies looking for even greater efficiencies, the need to re-use not only hardware but software components is essential. Enormous investments in legacy systems cannot be disposed of so the ME7834 mobile device test platform provides the most flexible way to combine existing and new components.
Rogers Corp.'s RT/duroid® 6035HTC is a high-thermal-conductivity (HTC) laminate material engineered for low loss in high power circuits. The fluoropolymer composite material is ideal for RF and microwave applications in military and high reliability (hi-rel) applications required to handle high power levels, such as power amplifiers. Rogers RT/duroid 6035HTC laminates feature a relative dielectric constant of 3.5 at 10 GHz.
Comsol reveals the Batteries & Fuel Cells Module which is a specialized tool designed to model and simulate all types of battery and fuel cell (FC) applications. The Module features tailored general interfaces to study primary, secondary and tertiary current density distributions in electrochemical cells, and specialized interfaces for lithium-ion, nickel-metal hydride and lead-acid battery chemistries.
Specially designed for USB super users, such as video and audio techs, the 4-Port Lab Brick® USB Hub from Vaunix offers the highest power in the industry and delivers it to all ports simultaneously and continuously.
MITEQ introduces a family of broadband amplifiers that cover 4-8 GHz with minimum 36 dB gain, typical 34 dBm P1dB, 40 dBm output IP3, and a very low noise figure. The AMF-4B-04000800-50-33P is a balanced amplifier with excellent gain flatness to within ±1 dB typical over the full band.
The Model AMF-6B-08501070-80-33P-ISO delivers over 33 dBm of power over the band 8.5 to 10.7 GHz, with over 30 dB gain and ±0.75 dB flatness. P1 dB is over 34 dBm above 10 GHz. Noise figure is less than 8 dB, port VSWR is less than 1.5:1, and it draws about 1.4A from a single +12 to +15 V DC supply.
The ANG series of noise generators provide up to 1 W of white Gaussian noise output in several models over the 10 Hz-18 GHz frequency range, with custom options to 40 GHz. Stock availability. The noise, which is diode generated, is amplified and the level can be varied in 1 dB steps from 0 to 10 dB or optionally in 0.1 dB steps from 0 to 111 dB.
