MAX2611 19-1094 Rev 2 4/05 DC-to-Microwave, Low-Noise Amplifier General Description Features The MAX2611 is a low-voltage, low-noise amplifier for Single +5V Supply Operation use from DC to microwave frequencies. Operating from 3dB Bandwidth: DC to 1100MHz a single +5V supply, it has a 3dB bandwidth of 1100MHz. The MAX2611s low noise figure and high High Gain: 18dB at 500MHz drive capability make it ideal for a variety of transmit, Low Noise Figure: 3.5dB at 500MHz receive, and buffer applications. In a typical application, the only external components High Drive Capability: +3dBm at 16mA I D needed are input and output blocking capacitors and Ultra-Small SOT143 Package a V series resistor. To improve gain and output CC 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.
