Introduction to Wireless Systems--A Tutorial--Part II
Articles 7/27/2008 1 comment
Here is the segment two of a multi-part series excerpted from 'Introduction to Wireless Systems.' Chapter 4 concentrates on Radio Frequency Coverage: Systems Engineering and Design. Introduction to Wireless Systems brings together the theoretical and practical knowledge readers need to participate effectively in the planning, design, or implementation of virtually any wireless system.
Low noise amplifier for GPS mobile phones
Articles 7/27/2008 Post a comment
Infineon Technologies has added to its portfolio with a high-sensitivity low noise amplifier (LNA) for GPS-enabled mobile phones. Bearing mobile phone design requirements in mind, the BGA715L7 has been optimised for high-sensitivity and immunity to interference of cellular signals.

Claiming a market first for precision clock management in embedded and handheld applications by providing per-channel output-enable controls, STMicroelectronics has unveiled the first six devices in a series of clock-distribution ICs.
Jennic set to demo video-over-wireless
Articles 7/23/2008 Post a comment
Wireless communications chip and software developer Jennic Ltd. (Sheffield, England) plans to demonstrate to the public the use of the IEEE 802.15.4 open radio standard for wireless transfer of video. Jennic plans to show the transfer at the Wireless Japan Show being held at the Big Sight International Exhibition Centre in Tokyo this week.
SPDT switch housed in miniature package
Articles 7/21/2008 Post a comment
Intended for engineers searching for ways to improve performance while reducing the size of their dual-band WiFi and UWB designs, NEC has developed an SPDT GaAs MMIC switch that delivers low insertion loss with high isolation over the 2.4 to 6.0 GHz frequency ranges.
Viewpoint: Analog IP integration needs support
Articles 7/21/2008 1 comment
As end products get smaller, designers are increasingly integrating analog and mixed-signal functionality onto SoCs. Analog IP suppliers must support design teams' lack of in-house integration expertise and guide them throughout the entire design cycle to ensure and expedite successful silicon results.

TI chip boosts range for Zigbee
Articles 7/16/2008 Post a comment
Texas Instruments will bolster the reach of Zigbee networks as much as ten-fold with the CC2591 that integrates a group of mainly passive components including a power amplifier, low-noise amplifier, balun, switches, inductors and RF-matching devices.
WSVGA chip suits mid-sized displays
Articles 7/15/2008 Post a comment
Supporting WSVGA (1024 x 600) resolution, Korean mixed signal company MagnaChip Semiconductor's latest TFT-LCD driver chip is one of the first of its kind for mid sized applications.
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
