The IC includes an upconversion mixer with variable gain control, an LO buffer, and a variable-gain PA driver for output power control. The MAX2383 is designed to support the IMT-2000 frequency band. It includes a differential IF input port, an LO input port, and PA driver input/output ports. The upconverter mixer incorporates an AGC with over 30dB of gain control. The IC provides automatic throttle-back of PA driver and mixer current as output power is reduced. The main signal path and the LO buffer can be shutdown independently. The on-chip LO buffer can be kept ON while the main transmitter path is being turned on and off to minimize VCO pulling during TX gated-transmission. The MAX2383 is specified for +2.7V to +3.0V single supply and is housed in an ultra-miniature 3 x 4 UCSP™ package for optimum cost- and space-reduction and for best RF performance.
