General Description
Features
ꢀ Dual-Band, Triple-Mode Operation
ꢀ +7dBm Output Power with -54dBc ACPR
ꢀ 100dB Power Control Range
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.
ꢀ Supply Current Drops as Output Power Is Reduced
ꢀ Dual Synthesizer for IF and RF LO
ꢀ Dual On-Chip IF VCO
ꢀ QSPI/SPI/MICROWIRE-Compatible 3-Wire Bus
ꢀ Digitally Controlled Operational Modes
ꢀ +2.7V to +5.5V Operation
ꢀ Single Sideband Upconverter Eliminates SAW
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
loading data on the SPI™/QSPI™/MICROWIRE™-com-
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.
