Description

The MAX2369 is a dual-band, triple-mode complete transmitter for cellular phones. 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.

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 sideband injection, and IF/RF gain balancing. It is packaged in a small (7mm × 7mm) 48-pin QFN package with exposed paddle.
