MAX2062
Dual 50MHz to 1000MHz High-Linearity,
Serial/Parallel-Controlled Analog/Digital VGA
General Description
Features
S Independently Controlled Dual Paths
The MAX2062 high-linearity, dual analog/digital variable-
gain amplifier (VGA) operates in the 50MHz to 1000MHz
frequency range with two independent attenuators in
each signal path. Each digital attenuator is controlled
as a slave peripheral using either the SPI-compatible
interface, or a 5-bit parallel bus with 31dB total adjust-
ment range in 1dB steps. An added feature allows
rapid-fire gain selection among each of the four steps,
preprogrammed by the user through the SPI-compatible
interface. A separate 2-pin control lets the user quickly
access any one of four customized attenuation states
without reprogramming the SPI bus. Each analog attenu-
ator is controlled using an external voltage or through the
SPI-compatible interface using an on-chip 8-bit DAC.

S 56dB Path Isolation (at 200MHz)
S Built-In 8-Bit DACs for Analog Attenuation Control
S Supports Four Rapid-Fire Preprogrammed
Attenuator States
Since each of the stages has its own external RF input
and RF output, this component can be configured to
either optimize noise figure (NF) (amplifier configured
first), OIP3 (amplifier last), or a compromise of NF and
OIP3. The device’s performance features include 24dB
amplifier gain (amplifier only), 7.3dB NF at maximum
gain (includes attenuator insertion losses), and a high
OIP3 level of +41dBm. Each of these features makes
the device an ideal VGA for multipath receiver and trans-
mitter applications.

In addition, the device operates from a single +5V
supply with full performance or a +3.3V supply for an
enhanced power-savings mode with lower performance.
The device is available in a compact 48-pin TQFN
