19-3508; Rev 0; 2/05 KIT .. ATION EVALU LE B A IL A AV 800MHz to 1000MHz Variable-Gain Amplifier with Analog Gain Control General Description Features - 800MHz to 1000MHz RF Frequency Range- - 39d Bm Constant OIP3 (Over All Gain Settings) - 23.5d Bm Output 1d B pression Point - 15.5d B Typical Gain at Maximum Gain Setting - 0.15d B Gain Flatness Over 100MHz Bandwidth - 4.5d B Noise Figure at Maximum Gain Setting (Using 1 Attenuator) - Two Gain-Control Ranges: 22d B and 44d B - Analog Gain Control - Single +5V Supply Voltage - Pin patible with MAX2057, 1700MHz to 2500MHz RF VGA - External Current-Setting Resistors Provide Option for Operating VGA in Reduced-Power/Reduced Performance Mode - Lead-Free Package Available - Note: Operation beyond this range is possible, but has not been characterized. The MAX2056 general-purpose, high-performance variable-gain amplifier (VGA) is designed to operate in the 800MHz to 1000MHz frequency range- . This device Features 15.5d B of gain, 4.5d B of noise figure, and an output 1d B pression point of 23.5d Bm. The MAX2056 also provides an exceptionally high OIP3 level of 39d Bm, which is maintained over the entire attenuation range. In addition, the on-chip analog attenuators yield infinite control and high attenuation accuracy over selectable 22d B or 44d B control ranges. Each of these Features makes the MAX2056 an ideal VGA for cellular band GSM, cdma2000®, W-CDMA, and i DEN® transmitter and power amplifier AGC circuits. The MAX2056 is pin patible with the MAX2057 1700MHz to 2500MHz VGA, making this family of amplifiers ideal for applications where a mon PC board layout is used for both frequency bands. The MAX2056 operates from a single +5V supply and is available in a pact 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. Applications GSM 850/GSM 900 2G and 2.5G EDGE Base Station Transmitters and...
