VHF-to-Microwave, +3V,
General-Purpose Amplifiers
_______________General Description
The MAX2630/MAX2631/MAX2632/MAX2633 are low-
voltage, 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, eliminat-
ing the need for external bias resistors or inductors. The
MAX2632/MAX2633 have a user-selectable supply cur-
rent, 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 cur-
rent. 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 VCC bypass capacitor.
The MAX2630 comes in a 4-pin SOT143 package, re-
quiring minimal board space. The MAX2631/MAX2632
come in small 5-pin SOT23 packages. The MAX2633
comes in a 6-pin SOT23 package.
