10.10.13 -- NASA Radar Prototype Can Locate Disaster Victims Under 30 Feet Of Rubble
Enabling Larger Phased-Array Radars With JESD204B By Thomas Neu, Texas Instruments
In an effort to keep up with evolving threats over the past 50 years, conventional radar with mechanically scanning antennas have been largely replaced with phased-array systems. The benefits of the phased array, or active electronically scanned-array (AESA), radar range from being able to use beamforming for improved range and better target accuracy to the elimination of hydraulics (and their potential failure).
Spotlight On Amplifiers
500W High-Power Amplifier, 3U Chassis Empower RF Systems continues to leverage next generation hardware and software architecture with the next series of the ‘’size matters” portfolio — 500W in 3U chassis.
Ka-Band TWT Amplifier This rack-mounted TWT (traveling wave tube) amplifier covers the 26.5- to 40-GHz frequency range. It’s ideal for applications involving RF components testing, ECM transmitters, EMC testing, test and measurement, RFI susceptibility testing, EW threat simulation, and much more.
Military Booster Amplifier AR Modular RF has made significant changes to its model AR-50 automatic band-switching JITC-certified RF booster amplifier. The newly released version of this portable, lightweight booster amplifier (designed for multi-band VHF/UHF tactical radio equipment) features an enhanced heat sink, which allows for greater heat dissipation.
1-GHz Ultra-Miniature Logarithmic Amplifier The Ultra-Miniature series of Logarithmic Amplifiers provide broadband performance and superb linearity over a wide temperature range. The UMLA range is robustly constructed in lightweight aluminum alloy housings and designed to withstand harsh mechanical environments.
X-Band Solid State Power Amplifier (SSPA) This X-band SSPA features high-efficiency GaN transistors, 900W pulsed modules, and 1.5-kW to 6-kW combined power. For a detailed description and information on its specifications, download the datasheet.
Micro L- And S-Band Power Amplifier The NW-SSPA-MICRO-5W-1.0-2.5 is a miniature power amplifier ideal for power-constrained RF telemetry and tactical communication systems due to its small size and power efficiency. Download the datasheet for a detailed description, as well as information on features and specifications.
Need enhanced RF performance, low noise, low stray capacitance, and tight tolerances?
(MSI) manufacturers thick/thin-film chip resistors, networks, arrays, terminations, MOS capacitors, and attenuators for medical, satellite, aerospace, military, microwave, and telecommunication industries. All have a frequency range of DC to 20 GHz.
Ciao Wireless Model CA56-G411 is a GaN-based amplifier optimized for standard weather radar applications among other radar types, with frequency coverage from 5.5 to 5.7 GHz. It has 35 dB of gain with +36 dBm output power at the 1-dB compression point and with up to +38 dBm of saturated output power from a +28 VDC supply.
An amplifier's true dynamic range is the range of input signals in which spurious outputs are below the noise level of the output. Engineers can choose from Teledyne Microwave Solutions' standard catalog solutions, or talk directly to a Teledyne Microwave Solutions application engineer for custom performance capabilities.
This general-purpose amplifier is offered in both medium power and low noise. It features super broadband performance with gain choice and a compact size and light weight. This amplifier is ideal for telecommunications, transceiver sub-assemblies, test instrumentation, and lab equipment applications.
This webinar will cover both new user interface features, such as advanced CAD fixing tools and application automation, as well as extensions to the computational kernel of FEKO, e.g. fast continuous far-field calculations, curvilinear higher order basis functions, extensions to the characteristic mode solver, etc. There is no cost to register for the webinar.
