The MAX2045/MAX2046/MAX2047 are low-cost, fully integrated vector multipliers that 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 MAX2045/MAX2046/MAX2047 operate from a 4.75V to 5.25V single supply. All devices are offered in a compact 5mm ✕ 5mm, 32-lead thin QFN exposed-paddle packages. The MAX2045/MAX2046/MAX2047 evaluation kits are available, contact factory for availability.
The Maxim MAX2045, MAX2046 and MAX2047 are low‑cost, fully integrated high‑gain vector multipliers designed for UMTS, DCS/PCS and GSM frequency bands. They provide differential RF inputs and outputs and can be controlled via voltage‑ or current‑mode DACs.
The devices operate from a 4.75 V to 5.25 V single supply, consume about 800 mW, and are offered in a compact 5 mm × 5 mm 32‑lead thin QFN exposed‑paddle package. Detailed electrical characteristics, absolute maximum ratings and typical performance graphs are provided for each part.
