The MAX2361 dual-band, triple-mode complete transmit-

ter for cellular phones represents an integrated and archi-

tecturally advanced solution for this application. The

device takes a differential I/Q baseband input and con-

verts it up to IF through a quadrature modulator and IF

variable-gain amplifier (VGA). The signal is then routed to

an external bandpass filter and upconverted to RF

through an image-reject mixer and RF VGA. The signal is

further amplified with an on-chip PA driver. An IF synthe-

sizer, an RF synthesizer, a local oscillator (LO) buffer, and

a 3-wire programmable bus complete the basic functional

blocks of this IC. The MAX2363 supports single-band, sin-

gle-mode (PCS) operation. The MAX2365 supports sin-

gle-band cellular dual-mode operation.

The MAX2361 enables architectural flexibility because

of its two IF voltage-controlled oscillators (VCOs), two IF

ports, two RF LO input ports, and three PA driver output

ports. The devices allow the use of a single receive IF

frequency and split-band PCS filters for optimum out-of-

band noise performance. The low-noise PA drivers

allow up to three RF SAW filters to be eliminated. Select

a mode of operation by loading data on the

SPI

bus. Charge-pump current, IF/RF gain balancing,

standby, shutdown plus additional functions, are also

controlled with the serial interface.

The MAX2361/MAX2363/MAX2365 come in a 48-pin

TQFN-EP and QFN-EP package and are specified for

the extended (-40°C to +85°C) temperature range.
