Maxim MAX2633EUK-T, MAX2631EUK-T, MAX2630EUS-T Datasheet

_______________General Description
The MAX2630/MAX2631/MAX2632/MAX2633 are low­voltage, low-noise amplifiers for use from VHF to microwave frequencies. Operating from a single +2.7V to +5.5V supply, these devices have a flat gain response to 900MHz. Their low noise figure and low supply current make them ideal for receive, buffer, and transmit IF applications.
The MAX2630/MAX2631 are biased internally, eliminat­ing the need for external bias resistors or inductors. The MAX2632/MAX2633 have a user-selectable supply cur­rent, which can be adjusted by adding a single external resistor. This allows customized output power and gain according to specific applications requirements. The MAX2631/MAX2633 feature a shutdown pin that allows them to be powered down to less than 1µA supply cur­rent. Aside from a single bias resistor required for the MAX2632/MAX2633, the only external components needed for this family of amplifiers are input and output blocking capacitors and a VCCbypass capacitor.
The MAX2630 comes in a 4-pin SOT143 package, re­quiring minimal board space. The MAX2631/MAX2632 come in small 5-pin SOT23 packages. The MAX2633 comes in a 6-pin SOT23 package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

NAME
BIAS51
Amplifier Input. Use a series blocking capacitor with less than 3reactance at your lowest operating frequency.
Ground Connection. For optimum performance, provide a low­inductance connection to the ground plane.
Amplifier Output. Use a series blocking capacitor with less than 3reactance at your lowest operating frequency.
Supply Connection. Bypass directly at the supply pin. The value of the bypass capacitor is determined by the lowest operating frequency, and is typically the same as the blocking capacitor value. Additional bypassing may be necessary for long V
CC
lines. Shutdown Input. Driving SHDN with a logic low turns off the
amplifier.
FUNCTION
Bias Resistor Connection. Connect a resistor to GND to set the bias current. See the Supply Current vs. R
