High-Gain Vector Multipliers

General Description

Features

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.

ꢀ Multiple RF Frequency Bands of Operation

2040MHz to 2240MHz (MAX2045)

1740MHz to 2060MHz (MAX2046)

790MHz to 1005MHz (MAX2047)

ꢀ

0ꢀ2dB ꢁain Flatness

1ꢂ Phase Flatness

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.

ꢀ 3dB Control Bandwidth: 260MHz

ꢀ 15dBm Input IP3

ꢀ 15dB ꢁain Control Range

ꢀ Continuous 360ꢂ Phase Control Range

ꢀ 6ꢀ5dB Maximum ꢁain for Continuous Phase

The MAX2045/MAX2046/MAX2047 operate from a 4.75V

to 5.25V single supply. All devices are offered in a com-

pact 5mm ✕ 5mm, 32-lead thin QFN exposed-paddle

packages.

ꢀ Single 5V supply

The MAX2045/MAX2046/MAX2047 evaluation kits are

available, contact factory for availability.
