Researchers under DARPA’s Terahertz Electronics (THz) program have designed and demonstrated a 0.85 Terahertz power amplifier using a micromachined vacuum tube—a world’s first. The achievement comes from DARPA-funded researchers at Northrop Grumman Electronic Systems, who built the 1 centimeter-wide traveling wave vacuum tube. The vacuum tube power amplifier is only one achievement of the broader THz program, which seeks to develop a variety of breakthrough component and integration technologies necessary to one day build complex THz circuits for communications and sensing.
Agilent Technologies Inc. announced the name of the electronic measurement company it expects to spin off in early November 2014 as Keysight Technologies. The name Keysight conveys the ability to see what others cannot, offering the critical or key insights to understand and unlock the changing technology landscape. The new company’s tagline, “unlocking measurement insights for 75 years,” commemorates the 1939 birth of the original Hewlett-Packard Company, from which Keysight originated. “Keysight reflects our rich heritage—a direct line from both Hewlett-Packard’s standards of integrity and innovation and Agilent’s premier measurement business,” said Ron Nersesian, president and CEO of Keysight.
Planar Monolithic Industries announced that its technical paper, "The Design of Ultra Narrow-band Amplifiers using Small Signal Varactor Up-converters for ESM, ECM, ECCM, and ELINT Applications,” was accepted for presentation at the Third International Conference on Electronic Warfare, Bangalore, February 17 – 20. The paper was authored by Dr. Alfred I. Grayzel, Dr. Ashok (Ash) K. Gorwara, and PaulKuhn, Planar Monolithics Industries, Inc., Frederick, Maryland.
Model AHP2475-03-3433-W42 is a temperature compensated waveguide power amplifier offering 34 dB linear gain and 33 dBm typical output power at 1 dB gain compression point over the frequency range from 24.0 to 25.5 GHz with excellent gain flatness as well as good temperature stability. The amplifier requires a single DC power supply +8.5~10.0 V. The package size of the amplifier is 1.7 × 1.2 × 0.40”.
Integrated Microwave bandpass filters can be supplied in a variety of different technologies, including but not limited to coaxial ceramic, cavity, lumped, helical, waveguide, tubular and microstrip. Chebyshev response filters are available, as well as Bessel, Gaussian, linear phase, Butterworth, elliptical and other transfer function filters.
The LTC3875 is a dual output current-mode synchronous step-down DC/DC controller that enables the use of very low DC resistance (DCR) power inductors by using a novel DCR sensing architecture that enhances the signal-to-noise ratio of the current sense signal. Power inductor DCR as low as 0.2 milliohms can be used without a sense resistor to maximize converter efficiency and increase power density.
Power Sensor w/ Long Reach Connector
LadyBug Technologies’ new extended N connector is ideal for many laboratory, manufacturing and field applications.
