250MHz to 4000MHz Dual,

Analog Voltage Variable Attenuator

General Description

Features

S 250MHz to 4000MHz RF Frequency Range

The MAX19790 dual, general-purpose analog voltage

variable attenuator (VVA) is designed to interface with

50I systems operating in the 250MHz to 4000MHz fre-

quency range. Each attenuator includes a patented con-

trol circuit that provides 22dB of attenuation range with a

linear control slope of 10dB/V.

S Integrates Two Analog Attenuators in One

Monolithic Device

S Flexible Attenuation-Control Ranges

22dB (per Attenuator)

44dB (Both Attenuators Cascaded)

Both attenuators share a common analog control and

can be cascaded together to yield 44dB of total dynamic

range, with a combined linear control slope of 20dB/V.

S 2.4dB 1500MHz Insertion Loss (per Attenuator)

S Linear dB/V Analog Control Response Curve

Simplifies Automatic Leveling Control and

Gain-Trim Algorithms

The IC is a monolithic device designed on one of Maxim’s

proprietary SiGe BiCMOS processes. The device oper-

ates from a single +5.0V supply and is available in a com-

pact, 36-pin thin QFN package (6mm x 6mm x 0.8mm)

with an exposed pad. Electrical performance is guaran-

teed over the extended -40° to +85°C temperature range.

S Excellent Attenuation Flatness Over Wide

Frequency Ranges and Attenuation Settings

S Low 7.3mA Supply Current

S Single +5.0V Supply Voltage

Applications

Broadband System Applications, Including

Wireless Infrastructure Digital and Spread-

Spectrum Communication Systems
