♦ 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

_______________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:

pin must be RF bypassed for correct opera-

tion. To accomplish this, connect a capacitor between

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.
