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 applica-
tion, the only external components needed are input
and output blocking capacitors and a V
capacitor.
The MAX2650 comes in a 4-pin SOT143 package,
requiring minimal board space.
