19-2728; Rev 0; 1/03 High-Gain Vector Multipliers General Description 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 currentmode DAC. An internal 2.5V reference voltage is provided for applications using single-ended voltage DACs.
