High-Gain Vector Multipliers

Highly Integrated, Constant Group-Delay Vector Multipliers Reduce cost, Improve ACLR

Product Details

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.

Description

The MAX2045/MAX2046/MAX2047 evaluation kits (EV kits) simplify evaluation of the MAX2045/MAX2046/MAX2047 vector multipliers. Each kit enables testing of the device's RF performance and requires no additional support circuitry. The EV kit input and output use SMA connectors and baluns (for single-ended-to-differential conversions) to facilitate the connection to RF test equipment.

Each EV kit is assembled with either the MAX2045, MAX2046, or MAX2047 and incorporates all matching components optimized for the corresponding band of frequency operation.
