Specifications of MAX2056EVKIT

• Frequency: 800MHz ~ 1GHz
• For Use With/related Products: MAX2056
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

The MAX2056 general-purpose, high-performance VGA
with analog gain control is designed to interface with
50Ω systems operating in the 800MHz to 1000MHz fre-
quency range.
The MAX2056 integrates two attenuators to provide
22dB or 44dB of precision analog gain control, as well
800MHz to 1000MHz Variable-Gain
Amplifier with Analog Gain Control

as a two-stage amplifier that has been optimized to
provide high gain, high IP3, low noise figure, and low-
power consumption. The bias current of each amplifier
stage can be adjusted by individual external resistors
to further reduce power consumption for applications
that do not require high linearity.
