Pulse Introduces an Industrialized LTE Antenna that Adjusts to 7 Bands

Pulse Electronics, a worldwide leader in electronic component and subassembly design and manufacturing, introduces the first long-term evolution (LTE) antenna that can adjust to 7 bands: LTE 700, 850, 900, 1800, 1900, 2100, and 2600 megahertz (MHz)Built on the smallest LTE antenna platform available. The antenna is for use in small portable LTE devices such as mobile phones, wireless routers, and wireless modems. The antenna was designed to meet future demands for world phones with truly global roaming that also work seamlessly in LTE multiple-input, multiple-output (MIMO) networks while providing normal WCDMA, CDMA, and GSM access.

The adjustable single-element antenna requires only a single feed to cover all seven cellular operating bands with no market-specific versions needed comes in an extremely compact size of 50.2 x 18.0 x 6.9 millimeters, which includes volume for speakers and other accessories within the antenna frame structure.

Pulse’s LTE antenna is manufactured using Laser Direct Structuring (LDS) technologyLDS enables finer tuning of the antenna during production by allowing for finer line width and spacing than any other 3D antenna manufacturing technology on the market. 3D shapes are needed to achieve ever smaller and thinner mobile devices. They provide better RF performance by optimizing the space available for the antenna and permit more design freedom, especially in the case of the round shape.

LTE provides the ability to deliver high data rates to a variety of consumer devices including Mobile Internet Devices (MIDs) and smartphones. To achieve maximum data rate, the current LTE standard calls for MIMO antenna technology, or using two separate antenna structures for multiple transmitting and receiving signals. The Pulse LTE antenna has been characterized in 2x2 MIMO implementation. The antenna configuration has two ports and diversity in all operating frequencies. The required antenna volume is small and there is significantly lower correlation between antennas than seen in any other handset MIMO configurations.

“Pulse wanted a universal, truly global antenna solution, and we believe this new 7-band antenna meets that goal,” said Maritta Timosaari, director sales and marketing, Pulse Finland Oy. “Thus far, to our knowledge, only 4-5 band industrialized solutions are available in the market, and very little work has been done with MIMOs. Until now, almost all MIMO solutions have been demonstrated only on a single band. Pulse’s 7-band LTE antennas are a natural evolution of Pulse’s switchable antenna family, which has been available since 2003. Based on Pulse’s well-known and proven antenna technology, they are readily available, are of high quality, and come with Pulse service and support.”

Pulse's 7-band LTE antennas are RoHS compliant and meet LTE, WCDMA, CDMA, GSM, and TD-SCDMA standards. They are packaged in trays. Engineering samples are available.

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

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
