MAX2045/MAX2046/MAX2047 19-2728 Rev 0 1/03 High-Gain Vector Multipliers General Description Features The MAX2045/MAX2046/MAX2047 low-cost, fully inte- Multiple RF Frequency Bands of Operation grated vector multipliers alter the magnitude and phase 2040MHz to 2240MHz (MAX2045) of an RF signal. Each device is optimized for the UMTS 1740MHz to 2060MHz (MAX2046) (MAX2045), DCS/PCS (MAX2046), or cellular/GSM 790MHz to 1005MHz (MAX2047) (MAX2047) frequency bands. These devices feature differential RF inputs and outputs. 0.2dB Gain Flatness The MAX2045/MAX2046/MAX2047 provide vector 1 Phase Flatness adjustment through the differential I/Q amplifiers. The 3dB Control Bandwidth: 260MHz I/Q amplifiers can interface with voltage and/or current digital-to-analog converters (DACs). The voltage inputs 15dBm Input IP3 are designed to interface to a voltage-mode DAC, while 15dB Gain Control Range the current inputs are designed to interface to a current- mode DAC. An internal 2.5V reference voltage is provid- Continuous 360 Phase Control Range ed for applications using single-ended voltage DACs. 6.5dB Maximum Gain for Continuous Phase The MAX2045/MAX2046/MAX2047 operate from a 4.75V On-Chip Reference for Single-Ended to 5.25V single supply. All devices are offered in a com- pact 5mm 5mm, 32-lead thin QFN exposed-paddle Voltage-Mode Operation packages. 800mW Power Consumption The MAX2045/MAX2046/MAX2047 evaluation kits are Space-Saving 5mm x 5mm Thin QFN Package available, contact factory for availability.
