The MAX2045/MAX2046/MAX2047 low-cost, fully inte-
grated 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 provid-
ed 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 com-
pact 5mm
packages.
The MAX2045/MAX2046/MAX2047 evaluation kits are
available, contact factory for availability.
