General Description
The MAX19792 dual general-purpose analog voltage
variable attenuator (VVA) is designed to interface with
50I systems operating in the 500MHz to 4000MHz
frequency range. The device includes a patented control
circuit that provides 23.2dB of attenuation range (per
attenuator) with a typical linear control slope of 8.5dB/V.
Both attenuators share a common analog control and
can be cascaded together to yield 46.4dB of total attenu-
ation range with a typical combined linear control slope
of 17dB/V (5V operation).
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.
The MAX19792 is a monolithic device designed using
one of Maxims 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.
