MAXIM MAX2630, MAX2633 User Manual

_______________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.

NAME

BIAS51

Amplifier Input. Use a series blocking capacitor with less than
3Ω reactance 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
3Ω reactance 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
