Latvijas Mobilais Telefons SIA (LMT), Latvia’s first mobile network operator, has selected NEC to supply a national Packet Transport Network (PTN). The backbone network will support next-generation mobile backhaul services with transmission speeds of 10 Gbps. NEC will equip more than 50 nodes with its MN5000 Series PTN solutions....

UK-based picocell and femtocell developer and manufacturer, ip.access , has secured a dedicated R&D centre in India in partnership with worldwide business services company, Quickstart Global . Based at the Quickstart Global centre in Pune, the ip.access facility will initially number some 10 to 15 staff, but is expected...

Homatic A/S and Terma have signed an agreement that aims to intensify their cooperation, something the two companies have enjoyed for a number of years. Homatic supplies Terma with high-tech solutions including measurement and test equipment in connection with development of space equipment. Thorvald Horup, Managing Director of Homatic,...

EADS has opened a high technology demonstration laboratory at its Ottobrunn, Germany facility, providing a showcase for the company’s leading-edge research and development in areas of security, mobility, the environment and maintenance. The laboratory was unveiled by Jean Botti, Chief Technical Officer of EADS, in the presence of German...

AtlantecRF , the UK-based microwave components and equipment manufacturer, considers that its new amplifier could possibly be the most versatile in the world in that it is capable of operating over a temperature range from -269°C (4K) to +100°C at frequencies from 1 to 20 GHz. Model AOX-010200 is...

Microwave power devices have recently played an important role in wireless communication systems, in which both the output power density and the device linearity are key factors in increasing the dynamic range, while satisfying the linearity requirements. The electric field profile across the channel of a PHEMT is a...

Ultra-wideband (UWB) technology has been a key issue in the development of new high speed indoor and hand-held wireless communication systems since the unlicensed use of UWB was approved worldwide. As one of the essential components in UWB communication systems, the UWB bandpass filter (BPF), with such characteristics as...

There has recently been an exponential growth in worldwide wireless communications. The IEEE 802.11 group has been responsible for setting up standards, including those for wireless local area networks (WLAN), and dual-band communication at 2.4 GHz (2400 to 2483.5 MHz) and 5.2 GHz/5.8 GHz (5150 to 5350 MHz and...

Commercially available RF, microwave and optical driver amplifiers provide their best performance under specific bias conditions. The quiescent current of such amplifiers affects critical performance parameters such as efficiency, inter-modulation distortion products and noise figure. Therefore, it is crucial to bias these amplifiers accurately for best performance. Some amplifier...

The increasing content of today's smartphones dictates shrinking form factors and increased flexibility in the RF Front-End (RFFE). Mainstream cellular devices support two bands of W-CDMA for home network data access and four bands of GSM/GPRS/EDGE for worldwide mobility. Focus on cost has driven the industry to reuse the...
