Description
Request Full Data Sheet
The MAX2599 complete monolithic direct-conversion I/Q transmitter is designed for WCDMA/HSPA femto basestation transmitter applications. The device is TS25.104 compliant in the 2110MHz to 2170MHz band.

The unique bits-to-RF architecture of the MAX2599 integrates a power amplifier (PA), a quadrature mixer, variable-gain RF and baseband amplifiers, baseband filters, I and Q digital-to-analog converters (DACs), and a fractional-N frequency synthesizer for local oscillator (LO) generation. Data is transferred from the baseband/DSP to the radio by a digital 1-bit sigma-delta modulated I and Q bitstream through an LVDS-like interface. The operating mode of the radio is fully programmable by a 3-wire serial interface.

The MAX2599 is specified for operation in the extended -40°C to +85°C temperature range and is available in a 9mm x 9mm x 1.4mm fcLGA package with exposed paddle (EP).
