EVALUATION PCB
AVAILABLE
DC-to-Microwave,
+5V Low-Noise Amplifier
_______________General Description
The MAX2650 is a low-noise amplifier for use from DC
to microwave frequencies. Operating from a single +5V
supply, it has a flat gain response to 900MHz. The
MAX2650’s low noise figure and high drive capability
make it ideal for a variety of transmit, receive, and
buffer applications.
The device is internally biased, eliminating the need for
external bias resistors or inductors. In a typical application, the only external components needed are input
and output blocking capacitors and a VCCbypass
capacitor.
The MAX2650 comes in a 4-pin SOT143 package,
requiring minimal board space.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
