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