MAX2361/MAX2363/MAX2365
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
™
/QSPI
™
/MICROWIRE
™
-compatible 3-wire serial
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.
