MAX2057ETX-MAX2057ETX+-MAX2057ETX+T
1300MHz to 2700MHz Variable-Gain Amplifier with Analog Gain Control
General Description
The MAX2057 general-purpose, high-performance vari-
able-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 out-
put 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 trans-
mitter and power amplifier AGC circuits.
The MAX2057 is pin compatible with the MAX2056
800MHz to 1000MHz VGA, making this family of ampli-
fiers 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 per-
formance is guaranteed over the extended -40°C to
+85°C temperature range.
