Figure 1. Typical Application Circuit
Detailed Description
The MAX2057 general-purpose, high-performance VGA
with analog gain control is designed to interface with
50 ? systems operating in the 1300MHz to 2700MHz
frequency range.
The MAX2057 integrates two attenuators to provide
21dB or 42dB of precision analog gain control, as well
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.
