Overview
Features and Benefits
Product Details
The MAX2056 general-purpose, high-performance variable-gain amplifier (VGA) is designed to operate in the 800MHz to 1000MHz frequency range†. This device features 15.5dB of gain, 4.5dB of noise figure, and an output 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, W-CDMA, and iDEN® transmitter 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 performance is guaranteed over the extended -40°C to +85°C temperature range.
