MAX2650 19-1135 Rev 1 8/03 DC-to-Microwave, +5V Low-Noise Amplifier General Description Features The MAX2650 is a low-noise amplifier for use from DC Internally Biased to microwave frequencies. Operating from a single +5V High Gain: 18.3dB at 900MHz supply, it has a flat gain response to 900MHz. The MAX2650s low noise figure and high drive capability 3.9dB Noise Figure make it ideal for a variety of transmit, receive, and Single +4.5V to +5.5V Operation buffer applications. -1dBm Output 1dB Compression Power The device is internally biased, eliminating the need for external bias resistors or inductors. In a typical applica- Low-Cost Silicon Bipolar Design tion, the only external components needed are input and output blocking capacitors and a V bypass Ultra-Small SOT143 Package CC capacitor. The MAX2650 comes in a 4-pin SOT143 package, requiring minimal board space.
