MAX2650
19-1135; Rev 1; 8/03 EVAALVUAAILTAIOBNLEKIT
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 VCC bypass capacitor.
The MAX2650 comes in a 4-pin SOT143 package, requiring minimal board space.
