The MAX2057 general-purpose, high-performance variable-gain amplifier (VGA) is designed to operate in the 1300MHz to 2700MHz 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 pad. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.ApplicationsAutomated Test Equipment (ATE)Broadband SystemscdmaOne™ and cdma2000® Base-Station Transmitters and Power AmplifiersDCS 1800/PCS 1900 2G and 2.5G EDGE Base-Station Transmitters and Power AmplifiersDigital and Spread-Spectrum Communication SystemsMicrowave Terrestrial LinksPHS/PAS Base-Station Transmitters and Power AmplifiersReceiver Gain ControlTransmitter Gain ControlTransmitters and Power AmplifiersTransmitters and Power AmplifiersWCDMA, LTE, TD-SCDMA, and TD-LTE Transmitters and Power Amplifiers
