Cellular Blade Antennas Deliver the Highest Radiated Efficiency Performance in a Standard Product

Pulse Electronics, a worldwide leader in electronic component and subassembly design and manufacturing, introduces its new cellular, penta-band blade antennas with cable and SMA connectors. These antennas deliver at least 50% radiated efficiency in all frequency bands
in which they operate while still providing voltage standing wave ratio (VSWR) figures of 1.5 decibels (dB). They provide a wireless connection to cellular networks using 850, 900, 1800, 1900, and 2100 megahertz (MHz) frequencies typical in GSM, CDMA, DCS, PCS, WCDMA, UMTS, HSPA, GPRS, 3G, and EDGE in platforms, in applications such as machine-to-machine (M2M), smart metering, monitoring, security, data logging, and data collection. They are a cost-effective M2M antenna for the industrial marketplace.

Pulse's penta-band blade antennas come in two configurations, the W1920G0915, which has a three-foot cable, and the W1920G3658, with a 12-foot cable. Measuring 110 x 22 x 5 millimeters and weighing 29 grams with the shorter cable, this is the smallest penta-band blade antenna capable of operating at 50% efficiency in every frequency band. Efficiency is important because it measures how much of the transmitted signal is actually used, rather than lost, by the antenna. The higher the efficiency, the less power is needed from the radio and the more economical the design. Greater efficiency also gives higher integrity to the data collection due to a greater signal emanating from the antenna.

A slightly flexible covering makes mounting easier and lowers the design cost as compared to a hard case antenna. It has a strong adhesive mounting and comes with an RG174 black cable and SMA male connector. Other specifications include a gain of minimum 1 decibel isotropic (dBi), a nominal impedance of 50 Ω, an omni-directional radiation pattern in the horizontal plane, vertical polarization, and a power rating of 3 watts.

“The W1920G0915 antenna gives M2M customers confidence in their cellular network connections,” said Elaine Baxter, marketing manager, Pulse Wireless Devices Antenna Division. “Its demonstrated efficiency exceeds the competition for this size of penta-band blade antenna.”

Pulse's penta-band blade antennas come packaged in bags with SMA connectors. The W1920G0915 and W1920G3638 are the SMA male versions with two cable length options. Custom cable options and alternative connectors are available upon request. They are easy to implement and come with Pulse's worldwide technical support. Prices for the W1920G0915 antennas are about $5.50 in quantities of 50,000 and for the W1920G3658 about $6.35 and may vary according to destination and order configuration. Delivery is about 8 weeks; products are available now.

Biasi Develops ActivA Unique Boiler Range Biasi UK has developed ActivA, a new range of high efficiency A rated condensing boilers boasting a unique heat exchanger. The launch of ActivA is further testimony to the company's commitment to strengthen its position in the UK domestic gas boiler market. At the heart of ActivA is a newly developed pre-mix condensing heat exchanger that is manufactured in a corrosion resistant, pressure moulded aluminium. Its sectional construction means it can be easily adjusted for different boiler outputs and its 'multipass' design ensures very low resistance for both combustion and water passage. This unique heat exchanger carries a five year guarantee. Designed to provide outstanding heating performance at an affordable price for almost all types of domestic properties, the compact range boasts some of the smallest boilers available - at just 700mm high x 400 wide and only 290mm deep - thereby allowing installation in cupboards.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as
