RF Solutions for the Automotive Market
Introduction
The automotive industry has been revolutionized with the increased adoption of telematics in vehicles including
GPS, Cellular, Bluetooth and Satellite Radio. No longer are satellite navigation systems and sophisticated in-vehicle
entertainment confined solely to the luxury end of the market.
As telematic advancements become more reliable, available and inexpensive, vehicles are transforming into an
intelligent platform for enabling mobile life. With these recent advancements in communications technology and
increased consumer demand for a diverse array of on-board telematics services, RF communications systems have
become integral components of today’s automobile, trucking, watercraft, motorcycle and off-road construction markets.
To keep RF interconnection costs low, and to ensure high levels of electrical and mechanical performance for
telematics applications, such as Global Positioning Satellite, Satellite Radio, Vehicular Internet Access, Remote vehicle
diagnostics and Bluetooth, the worldwide automotive industries have standardized a high-performing, cost-effective
RF connector based on the FAKRA and USCAR standards.
Utilizing a modified metal SMB connector embedded within a plastic housing that can be designed with multiple
color codes for easy identification, FAKRA connectors are designed to perform up to 6 GHz and meet the particular
mechanical and environmental requirements of the automotive industry. Amphenol RF also offers a variety of
connectors for board-to-board, PCB interfaces, and traditional antenna interfaces.
Technologies Supported
AM/FM Radio:
Antenna technology that supports GPS and Satellite Radio is the same antenna that will support
AM/FM radio. This combined antenna capability not only reduces the number of external antennas on the vehicles,
but offers standardization among the interconnects.
Satellite Radio:
Originating at a broadcast center, the broadcast signal is beamed from earth-station antennas
to broadcast satellites. These satellites don’t move and are positioned more than 22,000 miles above the earth in
geo-stationary orbit. Their beams combine to span the entire contiguous U.S. while remaining stationary with respect
to the land below.
GPS
(Global Positioning System): A worldwide MEO satellite navigational system formed by 24 satellites orbiting
the earth and their corresponding receivers on the earth. The GPS satellites continuously transmit digital radio signals
that contain data on the satellites’ location and the exact time to the earth-bound receivers.
Cellular/PCS
(Personal Communications Service): the U.S. Federal Communications Commission (FCC) term
used to describe a set of digital cellular technologies being deployed in the U.S. It is also referred to as digital cellular.
Bluetooth:
A short-range radio technology aimed at simplifying communications among Internet devices,
between devices and the Internet. It also aims to simplify data synchronization between Internet devices and other
computers.
Wireless Remote:
Remote starting, remote keyless entry and door/window controls are all supported by our
FAKRA products.
Vehicle Controls:
Adaptive Cruise Control, Collision Avoidance Systems and DSRC (Dedicated Short Range
Communications) are all evolving technologies that utilize FAKRA.
WiFi:
Many new automotive models are incorporating WiFi in to their Infotainment offerings. Our FAKRA
connectors support this emerging technology.

Product Overview
FAKRA Generation 1.0, 2.0, and 2.5
Product Overview
GENERATION 1.0
FAKRA Generation 1.0 utilizes a modified metal SMB connector
embedded within a plastic housing unit for ease of identification
and assembly. These plastic housings are designed with visually
and mechanically coded and keyed tooling to eliminate assembly
errors. Our standard FAKRA connectors are designed to perform
up to 6 GHz and meet the electrical, mechanical and environmen-
tal standards of the automotive industry. Generation 1.0 typically
features five separate component parts.
GENERATION 2.0
FAKRA Generation 2.0 offers reduced installation costs for our
customers via a pre-assembled housing unit. This pre-assembled
housing eliminates two loose components and their associated
assembly and handling costs. Due to this component reduction,
Generation 2.0 features three separate components to install
versus Generation 1.0’s five separate components.
GENERATION 2.5
FAKRA Generation 2.5 offers the same pre-assembled housing
units and design improvements as Generation 2.0, but center
contacts are provided on a tape and reel for automated distribu-
tion and placement.
