The MAX2063 high-linearity, dual digital variable-gain
amplifier (VGA) operates in the 50MHz to 1000MHz
frequency range. Each digital attenuator is controlled
as a slave peripheral using either the SPIK-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 between each of four steps,
preprogrammed by the user through the SPI-compatible
interface. A separate 2-pin control allows the user to
quickly access any one of four customized attenuation
states without reprogramming the SPI bus.
Since each of the stages has its own external RF input
and RF output, this component can be configured
to either optimize noise figure (amplifier configured
first) or OIP3 (amplifier configured last). The device’s
performance features include 24dB of amplifier gain
(amplifier only), 5.6dB noise figure (NF) at maximum
gain (including attenuator insertion losses), and a high
OIP3 level of +41dBm. Each of these features makes the
device an ideal VGA for multipath receiver and transmitter
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.
This device is available in a compact 48-pin thin QFN
package (7mm x 7mm) with an exposed pad. Electrical
performance is guaranteed over the extended tempera-
ture range, from T
