INDUSTRY NEWS...
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.
Power Amplifier
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”.
Bandpass Filters
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.
Controller
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. The high quality Type N-male connector (option XNM) is available on most LadyBug power sensors including its True RMS, Peak & Pulse and Pulse-Profiling sensors. LadyBug sensors provide high accuracy NIST-traceable RF Power measurements to below -60 dBm. A virtual power meter application is included with each sensor.
Synthesizers
The MLSP-Series of YIG-Based wideband synthesizers are ideal as the main local oscillators in receiving systems, frequency converters and test and measurement equipment. They provide 1 kHz frequency
resolution over the 18 to 33 GHz frequency range, in bands. Power levels of +13 dBm are provided and full band tuning speed is 6 mSec. The units are 5” x 3” x 1” high and fit a 2 slot PXI chassis.
Coaxial Connectors
SGMC Microwave is offering a new line of gold plated 1.0 mm to 2.4 mm Between-Series Precision Coaxial Connectors. 1.0 mm Male to 2.4 mm Female and 1.0 mm Female to 2.4 mm Male between-series adapters offer low VSWR, excellent performance up to 50 GHz, and rugged construction for repeatability & reliability. The 2.4 mm connector series is mechanically compatible and inter-mate-able with the 1.85 mm connector series.
Cable Assemblies
Coaxicom manufactures a broad line of standard and custom flexible, semi-rigid, and Ultra-Flex cable
assemblies. Low loss, high performance cables, as well as ruggedized assemblies suitable for production
environments are also available. Standard and custom flexible cable assemblies can be supplied using virtually all of the common RG Type Cables.
Connectors, Cable
SV Microwave designs and manufactures RF connectors, cable assemblies and passive components. With over 40 years of proven performance, SV Microwave manufactures a very broad range of RF and microwave products. Our product range includes standard off-the-shelf catalog items, but primarily custom designed products for special customer requirements.
Cable Assemblies
TRUcore™ series cable assemblies offer a new level of RF & microwave performance combined with superior mechanical and environmental durability. They are available for 18, 26.5, 40 and 50 GHz broadband electrical performance, and provide designers with a highly durable construction that will not degrade under real life torque, vibration, crush or kinking forces that may be found in critical RF applications.
