Maxim MAX2611EUS Datasheet
19-1094; Rev 0; 6/96
EVALUATION KIT
AVAILABLE
DC-to-Microwave, Low-Noise Amplifier
_______________General Description
The MAX2611 is a low-voltage, low-noise amplifier for
use from DC to microwave frequencies. Operating from
a single +5V supply, it has a 3dB bandwidth of
1100MHz. The MAX2611’s low noise figure and high
drive capability make it ideal for a variety of transmit,
receive, and buffer applications.
In a typical application, the only external components
needed are input and output blocking capacitors and
a VCCseries resistor. To improve gain and output
power, an RF choke can be added in series to the bias
resistor.
The MAX2611 comes in a 4-pin SOT143 package,
requiring minimal board space.
