250MHz to 4000MHz Dual,
Analog Voltage Variable Attenuator
19-5165; Rev 0; 3/10
General Description
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 control circuit
that provides 22dB of attenuation range with a linear
control slope of 10dB/V.
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.
The IC is a monolithic device designed on one of Maxims
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癈 temperature range.
