The MAX2045/MAX2046/MAX2047 low-cost, fully integrated vector multipliers alter the magnitude and phase of an RF signal. Each device is optimized for the UMTS (MAX2045), DCS/PCS (MAX2046), or cellular/GSM (MAX2047) frequency bands. These devices feature differential RF inputs and outputs.

The MAX2045/MAX2046/MAX2047 provide vector adjustment through the differential I/Q amplifiers. The I/Q amplifiers can interface with voltage and/or current digital-to-analog converters (DACs). The voltage inputs are designed to interface to a voltage-mode DAC, while the current inputs are designed to interface to a current-mode DAC. An internal 2.5V reference voltage is provided for applications using single-ended voltage DACs. The parts are ideal for CDMA, multicarrier CDMA, cdma2000®, and WB-CDMA applications.

The MAX2045/MAX2046/MAX2047 operate from a 4.75V to 5.25V single supply. All devices are offered in a compact 5mm x 5mm, 32-lead thin QFN exposed-paddle package.

The MAX2045/MAX2046/MAX2047 evaluation kits help speed designs. Contact factory for availability.
