The World's First Vector Analyzer
On display at the Rohde & Schwarz booth will be the world’s first vector analyzer, which was introduced in 1950. The company will also show the evolution of test and measurements instrumentation from back then to the newest product launches slated for the conference. Rohde & Schwarz will also demonstrate group delay, envelope tracking, PA measurements, and other radar, satellite, and transmit-receive measurement setups.
A VNA System for Greater Confidence
Released by Anritsu, the VectorStar ME7838 is a 70-kHz-to-145-GHz broadband vector network analyzer (VNA) system with a single-coax connection. The VNA promises greater confidence when performing on-wafer device characterization at 70 GHz and beyond. This is done by conducting a single sweep on a device over multiple RF, microwave, and millimeter-wave waveguide bands. In turn, engineers can create more accurate models with fewer design turns when devices are used in applications.
Electromagnetic Software Version 4.0
The latest version of Delcross Technologies’ Savant 4.0 is a high-frequency electromagnetic (EM) software aimed at analyzing the performance of antennas when installed on electrically large vehicles and platforms. Delcross teamed up with CST for the new version in order to provide integration between the full-wave 3D EM solvers in the latter’s CST MICROWAVE STUDIO 2014. The full-wave result in Savant can then be used to efficiently analyze the antenna’s performance when mounted on a vehicle, which may be thousands of wavelengths in size.
Square Inductors Optimize Coplanarity
Coilcraft will be showing off the new 1111SQ series of high-performance, square air-core inductors. Offering high Q factors (up to 200 at 400 MHz) and inductance values from 27 to 47 nH, the sprigs are engineered to have a unique, square shape that optimizes them for coplanarity. This results in a flat top and bottom for reliable pick and place operation and mechanical stability on the PC board.
System Supports 3 CC
Aeroflex’s TM500 LTE-A Test Mobile and E500 Capacity Test System will support the aggregation of three component carriers (3 CC) which allows mobile network operators to achieve data rates up to 450 Mbit/s on their LTE-A networks. According to a project manager at Aeroflex, the TM500 is the first commercial infrastructure test platform to offer 3 CC. The capability will enable network performance to be tested and validated ahead of the availability of end-user terminals.
Switched-Filter Banks Suited for Military Applications
Offering customer-defined passband frequencies from 20 to 7500 MHz with ultimate rejection to 20 GHz, API Technologies will be showcasing a new line of standard switched-filter banks. The devices use mechanically channelized, PIN-diode switch manifolds for lower insertion loss and high isolation while lumped-element filters help to increase rejection. Featuring rugged construction, the switched-filter banks are well suited for military and high-end commercial applications that require superior signal integrity, such as electronic warfare (EW) and electronic intelligence (ELINT).
UHF Antenna for White-Space Frequency Bands
Cobham will be highlighting a dual-polar UHF sector antenna for use in the white-space frequency bands. Available in 2-, 3-, and 5-GHz bands, the antennas can be used in conjunction with radios and with two-port diversity to provide non-line-of-sight (NLOS) connectivity and reliable communications in challenging environmental conditions. The wideband SA11-90-0.6VH/2178 antenna provides both vertical and horizontal polarizations.
Low-PIM Attenuator Debuts
The most recent debut from JFW is an RF low-passive-intermodulation (low-PIM) attenuator. The 50FLP-XXX-100 fixed attenuator boasts a maximum PIM reading of -155 dBc (-165 dBc typical). It covers 698 to 2700 MHz and is available in values of 5, 6, 10, 20, and 30 dB. The 50FLP series handles average RF power to 100 W while maintaining accuracy of +/- 0.75 dB and a typical voltage standing wave ratio (VSWR) of 1.3:1.
System for Terahertz Materials Characterization
At the Lake Shore Cryotronics booth, the company will be an integrated system for terahertz materials characterization. The 8500 Series terahertz system is a fully integrated hardware/software platform for the characterization of electronic, magnetic, and chemical materials. The system uses non-contact, terahertz-frequency energy and an integrated low-temperature, high-field cryostat to measure material spectroscopic responses across a wide range of frequencies, temperatures, and field strengths. It performs continuous-wave spectroscopic response measurements to derive key material properties, such as dielectric constant, dynamic conductivity, carrier scattering times and mobilities, vibrational resonances, and magnetic resonances.
Balun Provides Conversions Between Signals
Marki Microwave will display a host of mixers and other RF/microwave parts including the 300-kHz-to-36-GHz isolation balun. The balun provides conversions between balanced and unbalanced signals--primarily for device and system testing. It flaunts ±0.5 dB amplitude and ±3-deg. phase balance across the entire operating band. In addition, the two output ports are isolated from each other, making it insensitive to balanced-port termination and crosstalk between balanced ports. This new device nearly doubles the frequency range of available instrumentation baluns without increasing the low-end cutoff, which is so important for baseband data. In other words, it can operate with up to 40 Gb/s data streams. Additionally, its isolation makes it usable to extend a two-port VNA to differential testing capabilities without additional attenuation.
MEMS Products Offer Increased Sensitivity
Vectron International will be showcasing a microelectromechanical-systems (MEMS) product, which incorporates a single-crystal silicon resonator that is Epi-sealed in a vacuum. The resonator is 1/3000th the mass of a comparable quartz resonator. Due to its size, it boasts high shock tolerance and low aging, making the device well suited for military munitions and harsh environmental applications. Vectron’s HT-MM900A Military Temperature MEMS oscillator can operate as a reference clock for demanding applications while withstanding shock of 30,000g, providing vibration resistance of 70g, and offering g-sensitivity of 0.1 ppb/g. In addition, this MEMS oscillator can scale to smaller footprints and function with different supply voltages while operating from -55° to 125°C with a low-g-sensitivity, 5-x-7-mm temperature-compensated crystal oscillator (TCXO).
Rebranding Turns Out New Products
Agilent Technologies is expected to be putting forth a lot of effort into rebranding its Electronic Measurement Group as Keysight Technologies. In terms of products, the firm is expanding its lower-profile product offerings by introducing the M9393A. This 27-GHz, PXIe vector signal analyzer delivers microwave measurement technology in a PXI form factor. It is suited to the manufacturing and design validation of transmitters and components for radar, military, satellite, and commercial wireless communications.
Upgraded Handheld Analyzers
Also on hand at the show will be Agilent's FieldFox Handheld Analyzers, which have received an upgrade for radar installation and maintenance (I&M). As a result, the firm claims there is finally a viable alternative to expensive, lab-grade instruments that make time-consuming measurements. The analyzers even have a remote viewing iOS application for control and monitoring straight from an iPhone or iPad.
Identify Potential Design Problems with Increased Flexibility
ANSYS’ HFSS offerings now include linear circuit simulation as well as the RF and signal-integrity (SI) option packages. According to the company, these new features help users quickly identify potential design problems with increased flexibility. They also provide easier access to a complete set of analysis capabilities that can be leveraged throughout a high-frequency electromagnetic (EM) simulation flow.
With the addition of linear circuit analysis, HFSS allows engineers to design, simulate, and validate antennas, microwave components, and RF/microwave circuits. By adding the ANSYS RF option to HFSS, designers gain an RF simulation flow that offers the following: harmonic-balance circuit simulation for nonlinear microwave-circuit amplifier analysis; a 2.5D Method of Moments solver integrated in the HFSS 3D layout interface; and filter synthesis.
