General Description

The MAX2360 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 MAX2362 supports single-

band, single-mode (PCS) operation. The MAX2364

supports single-band cellular dual-mode operation.

The MAX2360 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 MAX2360/MAX2362/MAX2364 come in a 48-pin

TQFP-EP package and are specified for the extended

(-40°C to +85°C) temperature range.
