General Description
The MAX2369 is a dual-band, triple-mode complete
transmitter for cellular phones. The device takes a differ-
ential 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.
The MAX2369 is designed for dual-band operation and
supports TDMA for the PCS band as well as TDMA and
AMPS for the cellular band. The desired mode of
operation is selected by loading data on the SPI"/
MICROWIRE"-compatible 3-wire serial bus. The
MAX2369 then routes the signals to the appropriate ports
depending on which band is selected. The MAX2369
includes two RF LO input ports and two PA driver ports,
eliminating the need for external switching circuitry.
The MAX2369 takes advantage of the serial bus to set
modes such as charge-pump current, high or low side-
band injection, and IF/RF gain balancing. It is packaged
in a small (7mm
7mm) 48-pin QFN package with
exposed paddle.
