MAX2630–MAX2633
_______________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.

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.

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 50Ω
system at the minimum operating frequency. Use the following equation to calculate their minimum value:
CBLOCK =
53,000
Figure 1. MAX2630 Typical Operating Circuit
f
CBLOCK
ON
(pF)
SHDN
OFF
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.

PC Board Layout Example
Example PC board layouts are given in Figures 4 to 7.
They use FR-4 with a 31mil layer thickness between the
RF lines and the ground plane. The boards satisfy all of
the above recommendations.
