VHF-to-Microwave, +3V,

General-Purpose Amplifiers

_______________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 VCC 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.

______________________________________________________________Pin Description

		PIN
					NAME	FUNCTION
	MAX2630	MAX2631	MAX2632	MAX2633
	1	5	5	6	IN	Amplifier Input. Use a series blocking capacitor with less than
						3Ω reactance at your lowest operating frequency.
	2	2	2	2	GND	Ground Connection. For optimum performance, provide a low-
						inductance connection to the ground plane.
						Amplifier Output. Use a series blocking capacitor with less than
	3	3	3	3	OUT
						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
	4	4	4	4	VCC	frequency, and is typically the same as the blocking capacitor
						value. Additional bypassing may be necessary for long VCC
						lines.
						Shutdown Input. Driving SHDN with a logic low turns off the
	—	1	—	1	SHDN
						amplifier.
						Bias Resistor Connection. Connect a resistor to GND to set the
	—	—	1	5	BIAS	bias current. See the Supply Current vs. RBIAS graph in the
						Typical Operating Characteristics.
