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 1A 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.

_______________Detailed Description
The MAX2630-MAX2633 are broadband amplifiers with 3dB bandwidth greater than 1GHz. Their small size and internal bias circuitry make them ideal for applications where board space is limited. The MAX2632/MAX2633 have a user-selectable bias current that allows the user to set both gain and output power for a particular application, and the MAX2631/MAX2633 incorporate shutdown capability.

__________Applications Information
External Components
The MAX2630-MAX2633 are easy to use, as shown in the Typical Operating Circuit and Figures 1, 2 and 3. Input and output series capacitors may be necessary to block DC bias voltages generated by the amplifiers from interacting with adjacent circuitry. These capacitors must be large enough to contribute negligible reactance in a 50 system at the minimum operating frequency. Use the following equation to calculate their minimum value: CBLOCK = 53,000 f (pF)
OFF GND

CBLOCK SHDN BIAS IN IN
where f (in megahertz) is the minimum operating frequency. The VCC pin must be RF bypassed for correct operation. To accomplish this, connect a capacitor between the VCC pin and ground, as close to the package as is practical. Use the same equation given above (for DCblocking capacitor values) to calculate the minimum capacitor value. If the PC board has long VCC lines, additional bypassing may be necessary. This can be done farther away from the package, if needed. Proper grounding of the GND pin is essential. If the PC board uses a topside RF ground, connect it directly to the GND pin. For a board where the ground plane is not on the component side, the best technique is to connect the GND pin to it with a plated through-hole close to the package. An on-chip buffer at the MAX2631/MAX2633's SHDN pin makes bypassing this pin unnecessary except in very noisy applications. When RF filtering is needed, use a bypass capacitor similar to the one used on VCC. Since negligible current flows into this pin, additional RF filtering may be done with a series resistor. To set the MAX2632/MAX2633's supply current, connect a resistor from the BIAS pin to ground. To estimate the value of this resistor, refer to the graph Supply Current vs. R BIAS in the Typical Operating Characteristics.
