MAX2597 Femto基站比特至RF无线发送器

The MAX2597 complete monolithic Bands II and V direct-conversion I/Q transmitter is designed for downlink WCDMA femto-basestation transmitter applications.

The unique bits-to-RF architecture of the MAX2597 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 bit stream through an LVDS-like interface. The operating mode of the radio is fully programmable by a 3-wire serial interface.

The MAX2597 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 pad (EP).
