General Description
The MAX2366 dual-band, triple-mode complete transmit-
ter for cellular phones represents the most integrated and
architecturally advanced solution to date for this applica-
tion. The device takes a differential I/Q baseband input
and mixes 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 SSB mixer and RF VGA. The signal is further
amplified with an on-board PA driver. Dual IF synthesiz-
ers, dual RF synthesizers, a local oscillator (LO) buffer,
and a 3-wire programmable bus complete the basic func-
tional blocks of this IC. The MAX2367 supports single-
band, single-mode (PCS) operation. The MAX2368
supports single-band cellular dual-mode operation.
The MAX2366 enables architectural flexibility because
its two IF voltage-controlled oscillators (VCOs), two IF
ports, two RF LO input ports, and three PA driver output
ports allow the use of a single receive IF frequency and
split-band PCS filters for optimum out-of-band noise
performance. The PA drivers allow up to three RF SAW
filters to be eliminated. Select a mode of operation by

patible 3-wire serial bus. Charge-pump current, side-
band rejection, IF/RF gain balancing, standby, and
shutdown are also controlled with the serial interface.
The MAX2366/MAX2367/MAX2368 come in a 48-pin
QFN-EP package and are specified for the extended
(-40C to +85C) temperature range.
