General Description

The MAX2360 dual-band, triple-mode complete transmit­ter for cellular phones represents the most integrated and
architecturally advanced solution to date for this applica­tion. 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 synthesiz­ers, dual RF synthesizers, a local oscillator (LO) buffer,
and a 3-wire programmable bus complete the basic func­tional blocks of this IC. The MAX2362 supports single­band, 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
loading data on the SPI™/QSPI™/MICROWIRE™-com­patible 3-wire serial bus. Charge-pump current, side­band 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.

1 — 1 RFL

Transmitter RF Output for Cellular Band (800MHz to 1000MHz)—for both FM
and digital modes. This open-collector output requires a pull-up inductor to
the supply voltage, which may be part of the output matching network and
may be connected directly to the battery.

No Connection. Make no connection to these pins.N.C.

2 2 — RFH0

Transmitter RF Output for PCS Band (1700MHz to 2000MHz). This open­collector output requires a shunt inductor to the supply voltage. The pull-up
inductor may be part of the output matching network and may be connected
directly to the battery.

Open-Collector Output Indicating Lock Status of the IF and/or the RF PLLs.
Requires a pull-up resistor. Control using configuration register bit LD_MODEO,
LD_MODE1.

Power Supply

Digital Input. A logic low on IDLE shuts down everything except the RF PLL
and associated registers. A small R-C lowpass filter may be used to prevent
digital noise.

CC

Supply Pin for the Upconverter Stage. VCCmust be bypassed to system
ground as close to the pin as possible. The ground vias for the bypass
capacitor should not be shared by any other branch.

Digital Input. A logic low on TXGATE shuts down everything except the RF
PLL, IF PLL, IF VCO, and serial bus and registers. This mode is used for
gated transmission.

Differential Inputs to the RF Upconverter. These pins are internally biased to

1.5V. The input impedance for these ports is nominally 400Ω differential. The
IF filter should be AC-coupled to these ports. Keep the differential lines as
short as possible to minimize stray pick-up and shunt capacitance.

BIAS

Bias Resistor Pin. RBIAS is internally biased to a bandgap voltage of 1.18V. An
external resistor or current source must be connected to this pin to set the bias
current for the upconverters and PA driver stages. The nominal resistor value is
16kΩ. This value can be altered to optimize the linearity of the driver stage.

Input Pins from the 3-Wire Serial Bus (SPI/QSPI/MICROWIRE compatible).
An R-C filter on each of these pins may be used to reduce noise.
