USB-Capable Power Sensors Rohde and Schwarz (RandS) has announced the NRP Z85 and NRP Z86, wideband sensors that measure power from 50 to 40GHz, suitable for microwave and radar development, maintenance and research. Instead of a base unit, the sensors are connected to a PC via a USB interface. This cost-efficient solution displays envelope power over a dynamic range of 47 to +20dBm. High-resolution pulse analysis is another exceptional feature. Additionally, the RandS NRP Z85 and RandS NRP Z86 provide high-precision continuous-average measurements over the entire dynamic range from 60 to +20dBm. These performance characteristics make the sensors suitable for a variety of applications in the development and maintenance of microwave and radar systems as well as in the design and production of microwave components. The wideband power sensors can be operated from a PC via the RandS NRP Z4 USB adapter, or in combination with an RandS NRP/NRP2 power meter. They can also be connected t
Embedded Computer for Factory Robots and Vehicles Nexcom has expanded its range of fanless embedded systems with the launch of the NISE 2100A Series, designed for a host of industrial computing applications within extreme environmental conditions. Housed in a rugged aluminium chassis, NISE 2100A has been designed to operate in temperatures of between -20 to 70C. This feature enables NISE 2100A to function in the severe environmental conditions usually associated with factory automation, industrial automation or transportation. It incorporates a 1.8GHz Intel Atom D525 Dual Core processor with ICH8M PCH chipset. This advanced Intel-based technology boasts 50 per cent better performance than the previous generation of Atom N270 CPU, with only a small increase in power consumption. Using onboard DDR3 memory, NISE 2100A is capable of fulfilling mainstream market requirements for increased performance with lower system configuration costs. The NISE 2100A is suitable for a wide variety
Welded-Steel Housing for Industrial Hardware Amplicon's Industrial Computing group has released a range of industrial-grade cabinets suited to housing Amplicon's industrial rackmount computers, data communication and test equipment. Designed for the rigours of industrial-grade applications, the range is constructed from a rugged, welded-steel housing with mesh doors, to provide optimal airflow for the valuable industrial hardware contained within. Available in a wide range of sizes to suit the hardware required, with heights up to 45U and depths to 1,200mm, the cabinets have the potential to allow up to 45U of rackmount equipment to be consolidated into a compact 600 x 600mm footprint. With simplicity in mind the new range can be supplied as a fully integrated turnkey solution, supplied ready for use, or alternatively as a versatile starter kit, supplied with everything needed to get up and running with a customer's own cabinet integrations, including power distribution, ca
Smallest 4A Switching Regulator Simplifies Designs and Improves Reliability Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX15040, a low-voltage (2.4V to 3.6V), synchronous switching regulator in a 2mm x 2mm wafer-level package (WLP). This miniature step-down regulator integrates MOSFETs to simplify design, minimize EMI, improve reliability, and save board space. The MAX15040 operates from a fixed 1MHz switching frequency to further reduce total solution size, as it allows all-ceramic-capacitor designs. Offering efficiencies up to 94% at full load current (4A), this point-of-load regulator minimizes power loss in applications such as telecom, networking, and server equipment. Other features include an enable input and power-good indicator for power sequencing, adjustable soft-start for controlled turn on, and the ability to safely start up into a prebiased output. The MAX15040 provides ±1% output-voltage accuracy over temperature and is fully specified over the -40°C to
Satellite IF Switch IC Expands to Allow 16 Signals Maxim Integrated Products has introduced the Max12005, an 8 x 4 satellite IF switch IC that is flexible and adaptable to suit space-constrained, satellite IF distribution and multiswitch applications. Its 8 x 4 matrix is configured with an additional IF switch input so that it can expand to accept up to 16 satellite input signals. The Max12005 supports a single, quad low-noise block (LNB) with vertical or horizontal polarisation signals that can be matrix-switched to four satellite receivers. A configuration of eight satellite IF inputs to eight satellite receivers is also possible by using two Max12005 ICs and adding eight input splitters. Signal quality is maintained even with high cable-signal losses. Four integrated 9:1 multiplexers with variable-gain input and output amplifiers provide sufficient gain to compensate for the signal-path losses in the cable distribution and for switch insertion losses. To save space and cost, t
MEMS Oscillator has Low Power Consumption MSC now offers SiTime's SiT8004 MEMS oscillator in the 125 to 150MHz frequency range, with low standby current, suitable for use in 'green' DDR, SAS, SATA, HDMI and video pixel clock applications. Key features include 6.5mA typical power consumption and 1.2uA ultra-low standby current. Frequency stability of the oscillator device varies between +/- 20 and +/- 50ppm, according to the supply voltage of 1.8, 2.5, 2.8 or 3.3V applied. Four industry-standard packages from 2.5 x 2.0 to 7.0 x 5.0mm are available. Thanks to its 50 to 75 per cent lower power consumption compared to similar standard quartz oscillators, the SiT8004 is suitable for use in 'green' DDR, SSD, SAS, SATA, HDMI and video pixel clock applications as well as 1-Gigabit Ethernet, GPON and EPON network applications.
MLCC Capacitors can be Used in Harsh Environments Now available, Holy Stone's compact 'Verti-Zontal' (vertically oriented, horizontally stacked) MLCC capacitors are designed for applications with limited headroom, requiring a high-CV product. This SVZ Series orients individual capacitors vertically, limiting the overall height while the stack itself extends horizontally across the mounting area on the board. The low ESR design allows for very high CV in the available footprint space. The compact yet high-CV design of these Verti-Zontal stacks is suitable for power applications including input and output filters. Its lead frame construction isolates the MLCC from both thermal and mechanical stresses, which can be problematic with large capacitors. The Holy Stone design provides outstanding mechanical integrity as the design provides for individual leads to be centred on each cap insert. The low centre of gravity provides superior shock and vibration resistance, so they
