General Description
MAX2057 General Description
The MAX2057 general-purpose, high-performance variable- 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 output 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 transmitter and power amplifier AGC circuits.
The MAX2057 is pin compatible with the MAX2056 800MHz to 1000MHz VGA, making this family of amplifiers 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.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
