RF & Wireless NEMA-Rated

RF & Wireless NEMA-Rated Weatherproof Enclosures Transtector Systems released a new, comprehensive line of NEMA-rated weatherproof equipment enclosures that are engineered to securely protect mission-critical electronics and are available with same day shipping to meet crucial deadlines. The new TEF14- series includes 45 enclosure configurations and 15 essential accessories available for immediate shipment. The line features multiple configurations for global applications including industrial automation, SCADA, oil and gas, mining, transportation, public works, security and automation, and much more. Each enclosure provides vital protection for key electronic equipment, enhancing network security and reliability. Key features of the TEF14- series include: • weatherproof NEMA design in standard 14” x 12” x 7” sizes • rugged construction ideal for indoor and outdoor applications • fully gasketed raised lid for secure protection • pad lockable stainless steel quick release latches • UV stabilized polyester reinforced fiberglass construction • options include cooling fans, power sources, heaters, insulated, PoE, terminal blocks, DIN Rail, predrilled mounting plates, vents and UL listed configuration • replacement parts and mounting kits can be ordered separately Configurations include 120 V AC, 240 V AC, 12 V DC, PoE-ready and non-powered enclosures. This large selection of in-stock TEF enclosures is competitively priced to provide high-value performance. Custom modifications are also available. ■ Transtector www.transtector.com Waveguide-to-Waveguide Transitions Fairview Microwave, Inc. has launched a new line of waveguide transitions that operate from 5.85 to 110 GHz across 14 frequency bands. These waveguide adapters are ideal for high power wireless applications such as test benches, instrumentation, Milcom, Satcom, telecom and radar applications where signal strength and integrity are critical. Fairview’s new waveguide-towaveguide transition series consists of 23 unique models utilizing a range of waveguide sizes and frequencies. This product line allows for smooth transitions between different waveguide sizes with minimal loss and SWR as low as 1.08. Waveguide sizes in this line range from WR-10 to WR-137. They are offered with UG-style square cover and round cover flanges, CPRG-style or UBR-style flanges. These new waveguide transitions are made of rugged, gold-plated or painted brass, depending on the model. Mechanical lengths of these adapters range from 1 to 6 inches. All models are REACH and RoHS compliant. ■ Fairview Microwave, Inc. www.fairviewmicrowave.com Fractus Antennas Library for Smart IoT and 5G Devices To accelerate the development of wireless devices for Sigfox, LoRa, narrowband internet of things (NB-IoT), LTE-M, Bluetooth and other IoT and 5G/LTE networks, NI AWR Design Environment software now includes an extensible markup language (XML) library for compact, surface-mount antenna components from Fractus Antennas (NN). With the inclusion of these antenna parts, RF designers can rapidly address component integration on a printed-circuit board substrate through direct simulation of the Fractus Antennas part of choice, along with frontend components such as power amplifiers, low-noise amplifiers, and filters, as well as any required impedance matching. Front-end component-to-antenna matching can also be developed using the network synthesis module in Microwave Office circuit design software to ensure maximum power transfer between RF driving circuitry and the antenna. The Fractus Antennas XML library is available directly from within the elements tab of NI AWR Design Environment software. ■ NI AWR Software www.ni.com/awr New 650 V GaN E-HEMTs Richardson RFPD announced the availability and full design support capabilities for a new family of 650 V GaN E-HEMTs from GaN Systems Inc. The GS- 065-0xx-1-L devices are ideal for low power applications, including charging, power supplies, lighting and appliances. • industry standard 5 x 6 mm PDFN packages • assembly using standard SMT process • scalable: 3.5 to 11 A in the same footprint • fast, clean switching speed • high switching frequency (20 MHz) • low switching losses & EMI • high efficiency • Kelvin sense • zero Qrr • bottom side cooling ■ Richardson RFPD www.richardsonrfpd.com Frequency Synthesizer Operates at 640 MHz Z-Communications, Inc. announced a new RoHS compliant Fixed Frequency Synthesizer model SFS0640A-LF in the UHF frequency. The SFS0640A- LF is a single frequency synthesizer that operates at 640 MHz with an external 10 MHz reference and features a typical phase noise of -100 dBc/Hz, -105 dBc/ Hz, and -124 dBc/Hz at the 1 kHz, 10 kHz and 100 kHz offsets, respectively. The SFS0640A-LF is designed to deliver a typical output power of 0 dBm with a VCO voltage supply of 5 Vdc while drawing 25 mA (typical) and a phase locked loop voltage of 3 Vdc while drawing 9 mA (typical). This Fixed Frequency Synthesizer features a typical 2nd harmonic suppression of -13 dBc and spurious suppression of -70 dBc. It is housed in Z-COMM’s standard PLL-V12N package measuring 0.6 x 0.6 x 0.13 in. The SFS0640A-LF is also ideal for automated surface mount assembly and is available in tape and reel packaging. SFS0640A-LF is an excellent choice for test station and wireless radio applications, and is specified for operation over the industrial temperature range of -40 to +85 °C. ■ Z-Communications, Inc. www.zcomm.com Miniature Coaxial Rotary Joints RFMW, Ltd. announced design and sales support for API Technologies’ 351 single channel rotary joint. API rotary joints are used to transmit RF energy from a stationary RF source to a rotating RF line and find applications in military and commercial 66 hf-praxis 5/2019

RF & Wireless markets such as mobile satellite communication systems, radar systems including civil air traffic control, weather radars or anywhere rotational force might damage a transmission line. The 351 operates from DC to 40 GHz using 2.92 mm coaxial connectors. SWR is as low as 1.05. With power handling up to 500 watts peak or 50 watts average, this rotary joint is rated for up to 3 amps of DC current. The rotation rating of the API 351 is 250 RPM. ■ RFMW, Ltd. info@rfmw.com www.rfmw.com SMT Power Limiter Handles 500 W Peak RFMW, Ltd. announced design and sales support for a high power, SMT RF limiter. The RFuW Engineering model number RFLM-262322HC-151 protects S-Band receivers from 2.6 to 3.2 GHz and is capable of handling 500 W of Peak Power (1 µs pulse width and 5% duty cycle) while operating at 85 °C.
