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

Its small size and simple bias circuitry make it ideal for applications where board space is limited. Grounding Proper grounding of the GND pins is essential. If the PC board uses a topside RF ground, the GND pins should be connected directly to it. For a board where the ground plane is not on the component side, the best technique is to connect the GND pins to it through multiple plated through-holes. MAX2611 __________Applications Information External Components As shown in the Typical Operating Circuit, the MAX2611 is easy to use. Input and output series capacitors may be necessary to block DC bias voltages (generated by the MAX2611) from interacting with adjacent circuitry. These capacitors must be large enough to contribute negligible reactance in a 50 system at the minimum operating frequency. Use the following equation to calculate their minimum value: CBLOCK = 53,000 f (pF) PC Board Layout Example An example PC board layout is given in Figure 1. It uses FR-4 with 31mil layer thickness between the RF lines and the ground plane. This board satisfies all the above requirements. where f (in MHz) is the minimum operating frequency. Bias current is supplied to the MAX2611 through an external resistor and optional RF choke connected between VCC and the OUT pin. A bypass capacitor from VCC to GND may be necessary to isolate the VCC line from other circuitry. The resistor value determines the bias current from the following equation: ID = VCC - VD RBIAS where VD is the device voltage, nominally 3.8V. An optional RF choke can be added to improve the MAX2611's gain and output power. The choke should be large enough to reduce the loading effect that the bias resistor has on the amplifier output. This is a function of R BIAS , frequency of operation, and output impedance. EXPANDED VIEW Figure 1.
