Description

The MAX2547 direct-conversion RF-to-bits radio receiver is designed for Band I (1920MHz to 1980MHz) WCDMA/HSPA femto-basestation applications. The receiver also features a separate dedicated receive path for the 2110MHz to 2170MHz band that enables monitoring of macro cell downlink activity (sniffer mode).

The unique RF-to-bits architecture of the MAX2547 integrates 2 LNAs, quadrature mixers, baseband anti-aliasing filters, programmable gain baseband amplifiers, high dynamic range I and Q sigma-delta analog-to-digital converters (ADCs), a fractional-N frequency synthesizer for local oscillator (LO) generation, and a fractional-N frequency synthesizer for sampling clock generation. Data is transferred from the radio to the baseband/DSP by a digital 1-bit sigma-delta-modulated I and Q bitstream through an LVDS-like interface. All decimation, compensation, and channel filtering is performed in the digital domain. Digital IP blocks are available from Maxim. The operating mode of the radio is fully programmable by a 3-wire serial interface.

The MAX2547 is specified for operation in the extended -40°C to +85°C temperature range and is available in a 7mm x 7mm x 1.4mm fcLGA package with exposed paddle (EP).
