MAX2630, MAX2631, MAX2632, MAX2633 VHF-to-Microwave, +3V, General-Purpose Amplifiers

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, 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 V_CC bypass 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.
