MAX19791

50MHz to 4000MHz Dual Analog Voltage Variable

Attenuator with On-Chip 10-Bit SPI-Controlled DAC

General Description

Features

The MAX19791 dual general-purpose analog voltage

variable attenuator (VVA) is designed to interface with

50I systems operating in the 50MHz to 4000MHz

frequency range. The device includes a patented con-

trol circuit that provides 23dB of attenuation range (per

attenuator) with a typical linear control slope of 8dB/V.

S Wideband Coverage

 50MHz to 4000MHz RF Frequency Range

S High Linearity

 Greater Than +37.4dBm IIP3 Over the Full

Attenuation Range

 +22.6dBm Input P

1dB

Both attenuators share a common analog control and

can be cascaded together to yield 46dB of total attenua-

tion range with a typical combined linear control slope of

16dB/V (5V operation).

S Integrates Two Analog Attenuators in One

Monolithic Device

S Two Convenient Control Options

 Single Analog Voltage

Alternatively, the on-chip 4-wire SPI-controlled 10-bit

DAC can be used to control both attenuators. In addi-

tion, a step-up/down feature allows user-programmable

attenuator stepping through command pulses without

reprogramming the SPI interface.

 On-Chip SPI-Controlled 10-Bit DAC

S Step-Up/Down Pulse Command Inputs

S Flexible Attenuation Control Ranges

ꢀ23dB (Per Attenuator)

ꢀ46dB (Both Attenuators Cascaded)

The MAX19791 is a monolithic device designed using

one of Maxim’s proprietary SiGe BiCMOS processes. The

part operates from a single +5V supply or alternatively

from a single +3.3V supply. It is available in a compact

36-pin TQFN package (6mm x 6mm x 0.8mm) with an

exposed pad. Electrical performance is guaranteed over

the -40NC to +100NC extended temperature range.

S Linear dB/V Analog Control Response Curve

Simplifies Automatic Leveling Control and

Gain-Trim Algorithms

S Excellent Attenuation Flatness Over Wide

Frequency Ranges and Attenuation Settings

S On-Chip Comparator (for Successive

Approximation Measurement of Attenuator

Control Voltage)

Applications

Broadband System Applications, Including

Wireless Infrastructure Digital and

Spread-Spectrum Communication Systems

S Low 13mA Supply Current

S Single 5V or 3.3V Supply Voltage
