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
