LвЂ‰DESIGN FEATURES Robust, Quiet, Stable Power Supply
for Active Antenna Systems with
Built-In Protection and Diagnostic
Capabilities
by Sam Rankin and Steve Knoth
Introduction
The days of the simple car radio, like
the Mercedes dashboard shown in FigureВ 1, are over, supplanted by the era
of the automobile infotainment system
(see FigureВ 2). The venerable AM/FM
radio still holds a place at the infotainment table, but it now shares space
with digital audio broadcasting (DAB),
digital and high-definition television
(HDTV), satellite radio, integrated cell
phones, CD/DVD/MP3 players, global
positioning system (GPS) navigation
and video game systems.
Behind the dashboard, fueling
this wealth of information, are active
antenna systems. As infotainment
centers have expanded in complexity, the number of active antennas
needed to feed music and data into the
infotainment center has multiplied. It …
