RF & Wireless News

RF & Wireless News Design Workshop Technologies DRC and LVS Tools NI (formerly AWR Corp.) announced AWR Connected for DWT, a new NI AWR Design Environment flow that enables integration with Design Workshop Technologies’ (DWT) design-rule checking (DRC) and/or layout vs. schematic (LVS) tools for printed circuit board and module design. The new AWR Connected for DWT DRC and LVS flow can run in one of two ways: in the full view/DWT user-interface (UI) mode or transparently from within the Microwave Office UI. The AWR Connected for DWT DRC module is a full-featured DRC tool capable of complex layout rule checks that can be used as a sign-off tool. It is well suited to handle all angle geometries, making it extremely flexible and capable of locating errors. In addition, the integrated AWR Connected for DWT error viewer option makes it easy for users to find and fix layout faults. The AWR Connected for DWT LVS module provides designers with an efficient tool for detecting network mismatches occurring in the physical layout of microwave MMIC, PCB and module designs. Capable of extracting common devices like metal oxide semiconductor field-effect transistors (MOSFETS), bipolar junction transistors (BJTs), diodes, capacitors and resistors, as well as generic userdefined devices and spiral inductors, AWR Connected for DWT LVS produces an easy-to-understand report, which lists all sources of discrepancies it detects between the layout-generated netlist and the original netlist. Lastly, the integrated error viewer, as used for DRC, is even more effective for finding and fixing LVS errors due to the cross-probing capability. ■ NI National Instruments ni.com Components Advanced GaN and GaAs MMICs Custom MMIC debuted several new GaAs and GaN MMIC amplifiers, switches, and multipliers. Their latest products include two GaAs LNAs, the CMD228P4 and CMD229P4, and a GaAs passive doubler, the CMD225. The CMD228P4 is a broadband MMIC low noise amplifier that operates from 2 to 6 GHz, delivers 30 dB of gain and achieves a noise figure of 1.3 dB. The CMD229P4 is also a broadband low noise amplifier that operates from 5 to 11 GHz, delivers 27 dB of gain, and achieves a noise figure of 1.2 dB. Both LNAs are housed in a leadless, plastic 4 x 4 mm surface-mount package. The CMD225 is a passive doubler in die form that operates from 4 to 8 GHz, has 12 dB conversion loss, and achieves fundamental and 3rd harmonic rejections of greater than 38 dB and 50 dB, respectively. Applications for these components include military, space, test instrumentation and other high performance communications. ■ Custom MMIC www.custommmic.com Compact Frequency and Time Reference Module The C-FTRM from TRAK Microwave is a tactical Frequency and Time Reference Module in a 2.40” x 2.66” form factor. The module includes a 50-channel GPS receiver, low g-sensitivity 10 MHz double-oven crystal oscillator, plus time and frequency generation circuitry providing reference outputs of 10 MHz, 1 PPS and Time of Day (TOD). The C-FTRM can be synchronized from the internal C/A code GPS receiver, or from an external GPS 1 PPS signal. The external GPS is the primary reference, with automatic switching to the internal receiver if no external 1 PPS signal is present. This device provides fast time-to-lock of

RF & Wireless Components They are available in various metallization styles and plating options. The flat broadband performance of the new attenuators allows for the creation of automatic- and passive-link margin compensation on a wide variety of transmit and receive chain circuit applications. ■ Richardson RFPD www.richardsonrfpd.com Broadband Conical Inductors Coilcraft announced their newly expanded line of BCL/BCR Series conical inductors. The products are offered in two configurations. The BCR Series has a full-length cap to protect the coil and provide a large surface for pick and place. The BCL Series features “flying leads” to allow precise positioning and adjustment of the mounting angle. Both series are now offered in nine inductance values ranging from 0.22 to 8 µH. They were designed specifically for broadband and high frequency applications, operating as a series of narrow-band inductors across a frequency range of 10 MHz to 40 GHz. They are ideal for use in ultra-wideband bias Tees, where the conical inductor provides the path for the DC bias injection or extraction while isolating the power source from the active device. For lower frequency applications, Coilcraft also offers their 4310LC Series wideband bias chokes which provide flat bandwidth with high impedance to 6 GHz. ■ Coilcraft www.coilcraft.com RF Cable Assembly Designer Pasternack Enterprises, Inc. has just released their newest engineering resource called the Cable Assembly Designer. Pasternack’s new custom cable designer enables engineers and buyers to create customized RF cable assemblies that meet their specifications from any combination of compatible connectors and cables offered by the company. Pasternack stocks and builds the industry’s most comprehensive selection of RF cable assemblies, with over 250,000 possible combinations, all available to ship the same day they are ordered. Whether you are looking for a common off-the-shelf cable or something unique to your specifications, Pasternack’s new web tool allows you to build your own custom cable assembly from over 1,300 connector types and 115 different coaxial cables (including Twinax). The RF cable assembly designer from Pasternack lets the user select from a variety of connector and coax parameters that meet their specifications in any order they prefer, such as gender, polarity, body style, max frequency, impedance, coax attachment method and many more. After ensuring all of the parameters for the connectors and coax have been selected, including the desired cable length and quantity, an RFQ is sent to Pasternack’s sales and service team for immediate follow up with pricing, availability and a part number for the assembly. The RF cable assembly designer also allows the selection of numerous value-added services such as custom labeling, lead-free solder/RoHS compliance and custom booting/ heat shrink. ■ Pasternack Inc. www.pasternack.com News CST and Dassault Systèmes Partner for Electromagnetic Simulation CST - Computer Simulation Technology AG (CST), developer of the technology leading CST Studio Suite, and Dassault Systèmes, the 3DEXPERI- ENCE Company, world leader in 3D design software, 3D Digital Mock Up and Product Lifecycle Management (PLM) solutions, jointly announced a partnership to integrate 3D electromagnetic simulation technology from CST into Dassault Systèmes’ 3DEX- PERIENCE platform. High-tech, transportation & mobility, aerospace & defense, industrial equipment and other industries will soon have access to a best-in-class multi-physics simulation solution for the creation and design of smart objects. The Internet of Things market is expected to reach 26 billion units by 2020 as devices, cars and buildings are developed beyond form and function to digitally interact with the physical world. However, this connectivity can lead to electromagnetic interference between devices or other unintended consequences that degrade product performance, reliability and safety. The combination of Dassault Systèmes’ 3DEXPERIENCE platform with CST STUDIO SUITE technology will enable customers to create and analyze electromagnetic behavioral models that simulate device function in a wide range of frequencies. This capability enhances the 3DEXPERIENCE platform’s simulation applications for solving multiphysics challenges in several areas including hybrid vehicle drivetrains and wearable electronics. ■ CST - Computer Simulation Technology AG info@cst.com www.cst.com hf-praxis 8/2015 59
