Integrating V2V functionality at 5.9GHz into an existing quad-band antenna for automotive applications Download White Paper 1008Ko

A DSRC antenna integrated in an existing automotive roof-mount quad-band antenna (Cell, GPS & XM) is presented. VSWR, isolation and gain measurements are shown for this antenna. On-vehicle measurements show that a DSRC antenna with better than 2:1 VSWR and -5dBi vertical average gain at azimuth can be achieved with minimal effect on existing multi-band antenna.

This month, Future Electronics has 20 of Intersil's ISL8203MEVAL2Z evaluation boards to give away to EETimes Europe's readers. Worth 95 US dollars, the board was designed to demonstrate the performance of the ISL8203M dual step-down power module which integrates a PWM controller, synchronous switching MOSFETs, inductors, and passives all in a 9.0x6.5x1.83mm package.

The ISL8203M is rated for dual 3A output current or 6A current sharing operation with an input range of 2.85V to 6V. Each of the two channels employs the current mode pulse width modulation scheme for fast transient response and pulse-by-pulse current limiting.
