The MAX2056 general-purpose, high-performance vari-

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

800MHz to 1000MHz frequency range*. This device fea-

tures 15.5dB of gain, 4.5dB of noise figure, and an out-

put 1dB compression point of 23.5dBm. The MAX2056

also provides an exceptionally high OIP3 level of

39dBm, which is maintained over the entire attenuation

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

infinite control and high attenuation accuracy over

selectable 22dB or 44dB control ranges. Each of these

features makes the MAX2056 an ideal VGA for cellular

band GSM, cdma2000

ter and power amplifier AGC circuits.

The MAX2056 is pin compatible with the MAX2057

1700MHz to 2500MHz VGA, making this family of

amplifiers ideal for applications where a common PC

board layout is used for both frequency bands.

The MAX2056 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 pad. Electrical per-

formance is guaranteed over the extended -40°C to

+85°C temperature range.
