3.2 RF transceiver
MT6140 RF transceiver
MT6140 is a highly integrated RF transceiver IC for Global Systems for
Mobile communication (GSM850, GSM900), Digital Cellular communication
Systems (DCS1800), and Personal Communication Services (PCS1900) quad
band cellular systems. It includes four LNA's, two RF quadrature mixers, a
channel filter, a programmable gain amplifier for the receiver, two high
precision I/Q modulators for the quad band transmitter, on-chip regulators, and
a fully programmable sigma-delta fractional-N synthesizer with an on-chip
LC-tank VCO. The MT6140 includes control circuits to implement different
operating modes. The device is housed in a 40-pin QFN SMD package with a
paddle for additional grounding.
