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 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 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.

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

package (7mm x 7mm) with an exposed pad. Electrical

performance is guaranteed over the extended tempera-

ture range, from T
