♦ Single +2.7V to +5.5V Operation
The MAX2630/MAX2631/MAX2632/MAX2633 are low-
volta g e , low-nois e a mp lifie rs for us e from VHF to
microwave frequencies. Operating from a single +2.7V
to + 5.5V s up p ly, the s e d e vic e s ha ve a fla t g a in
response to 900MHz. Their low noise figure and low
supply current make them ideal for receive, buffer, and
transmit IF applications.
♦ Internally Biased (MAX2630/MAX2631)
♦ Adjustable Bias (MAX2632/MAX2633)
♦ 6.6mA Supply Current (insensitive to supply
voltage)
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 e xte rna l c omp one nts
needed for this family of amplifiers are input and output
♦ 1µA Shutdown Current (MAX2631/MAX2633)
♦ 3.7dB Noise Figure
♦ 13.4dB Gain
♦ Ultra-Small SOT Packages

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

_______________De t a ile d De s c rip t io n
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 appli-
cation, and the MAX2631/MAX2633 incorporate shut-
down capability.

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 inter-
acting with adjacent circuitry. These capacitors must be
large enough to contribute negligible reactance in a 50Ω
system at the minimum operating frequency. Use the fol-
lowing equation to calculate their minimum value:

practical. Use the same equation given above (for DC-
blocking capacitor values) to calculate the minimum
capacitor value. If the PC board has long V
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 con-
nect 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 V
Since negligible current flows into this pin, additional
RF filtering may be done with a series resistor.

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.
