Product Brief
PMB 6258
SMARTi DC+
EDGE RF Transceiver
S M A R T i D C + is the first proven EDGE RF transceiver solution in
high volume production offering outstanding RF performance for
GPRS and EDGE.
It is Infineon Technologies 4th generation of the widely successful
SMARTi family of single chip radio transceivers. SMARTi DC+ is
a EDGE quad-band (GSM850/900/1800/1900) radio transceiver
supporting worldwide roaming.
With SMARTi DC+ all functions required for a cost and board space
optimized state of the art EDGE radio are integrated. All variants of
a GSM product family from high end EDGE to low end speech only
can be realized with the same radio design, answering the needs of
time to market.
SMARTi DC+ is entirely controlable through a 3 wire bus and offers
a standard I/Q interface to a wide variety of BB solutions.
In combination with Infineons S-GOLD EDGE BB Modem a compact
system approach can be achieved, which results in a very cost
effective EDGE solution.
