The MAX2057 general-purpose, high-performance vari-

able-gain amplifier (VGA) is designed to operate in the

1700MHz to 2500MHz frequency range*. This device

features 15.5dB of gain, 6dB of noise figure, and an out-

put 1dB compression point of 23.8dBm. The MAX2057

also provides an exceptionally high OIP3 level of

37dBm, which is maintained over the entire attenuation

range. In addition, the on-chip analog attenuators yield

infinite control and high attenuation accuracy over

selectable 21dB or 42dB control ranges. Each of these

features makes the MAX2057 an ideal VGA for

DCS/PCS, cdma2000™, W-CDMA, and PHS/PAS trans-

mitter and power amplifier AGC circuits.

The MAX2057 is pin compatible with the MAX2056

800MHz to 1000MHz VGA, making this family of ampli-

fiers ideal for applications where a common PC board

layout is used for both frequency bands.

The MAX2057 operates from a single +5V supply and is

available in a compact 36-pin thin QFN package (6mm

x 6mm x 0.8mm) with an exposed paddle. Electrical

performance is guaranteed over the extended -40°C to

+85°C temperature range.
