MAX2057 19-3510 Rev 1 12/10 1300MHz to 2700MHz Variable-Gain Amplifier with Analog Gain Control General Description Features The MAX2057 general-purpose, high-performance vari- 1300MHz to 2700MHz RF Frequency Range* able-gain amplifier (VGA) is designed to operate in the 37dBm Constant OIP3 (Over All Gain Settings) 1300MHz to 2700MHz frequency range*. This device features 15.5dB of gain, 6dB of noise figure, and an out- 23.8dBm Output 1dB Compression Point put 1dB compression point of 23.8dBm. The MAX2057 15.5dB Typical Gain at Maximum Gain Setting also provides an exceptionally high OIP3 level of 37dBm, which is maintained over the entire attenuation 0.5dB Gain Flatness Over 100MHz Bandwidth range. In addition, the on-chip analog attenuators yield 6dB Noise Figure at Maximum Gain Setting (Using infinite control and high attenuation accuracy over 1 Attenuator) selectable 21dB or 42dB control ranges. Each of these features makes the MAX2057 an ideal VGA for Two Gain-Control Ranges: 21dB and 42dB DCS/PCS, cdma2000, W-CDMA, and PHS/PAS trans- Analog Gain Control mitter and power amplifier AGC circuits. Single +5V Supply Voltage The MAX2057 is pin compatible with the MAX2056 800MHz to 1000MHz VGA, making this family of ampli- Pin Compatible with MAX2056, 800MHz to fiers ideal for applications where a common PC board 1000MHz RF VGA layout is used for both frequency bands. External Current-Setting Resistors Provide Option The MAX2057 operates from a single +5V supply and is for Operating VGA in Reduced-Power/Reduced- available in a compact 36-pin thin QFN package (6mm Performance Mode x 6mm x 0.8mm) with an exposed pad. Electrical per- formance is guaranteed over the extended -40C to Lead-Free Package Available +85C temperature range. *Note: Operation beyond this range is possible, but has not been characterized.
