Description

The MAAM-011100 is an easy-to-use, broadband,

general purpose variable gain amplifier. Its over

30 dB gain range is controlled by a single control pin

and 50 Ω match is maintained over all settings.

The MAAM-011100 operates from 400 MHz to

20 GHz and features flat gain control from +10 dB to

-20 dB. At maximum gain setting (VC=Open) it

delivers up to +18 dBm power and under 5 dB noise

figure. Both reduce proportionally as gain is reduced

with VC. The input IP3 exceeds +15 dBm at max/min

gain settings. The device is typically biased with a

VD = +5 V, VG = -0.5 V, and a control of 0 V to -2 V.

Typical current is 70 mA with VG at -0.5 V

The MAAM-011100 is ideally suited for use as a

power amplifier driver, gain trimming block, or

temperature compensation in the receive or transmit

mode. Typical applications include Wi-Fi, LTE.

Point-to-Point, IMS, EW, and A&D systems.

This device is assembled in a leadless 1.5 X 1.2 mm

package that can be handled and placed with

standard pick and place assembly equipment.

Handling Procedures

Please observe the following precautions to avoid

damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive

to electrostatic discharge (ESD) and can be

damaged by static electricity. Proper ESD control

techniques should be used when handling these

devices.

Parts List

For proper MAAM-011100 operation a DC voltage

must be applied at the VG (-0.5V) and VD (+5V) pins

in that order. Adjusting VG from -0.2 V to -0.6 V will

change the quiescent current which can effect power

and linearity if set below or above 70 mA.

The gain of the MAAM-011100 is controlled with the

VC pin. The gain reduction is almost linear with VC

between 0 V to -2 V. Below -2 V internal ESD

protection diodes will draw increasing current. The

nominal open circuit voltage at the VC pin is +1 V

and produces maximum gain and power. Limiting

applications and zero crossing adjustment can be

done by adjusting the VG and VC pins together.

To bias properly, a DC voltage must be applied at

the output pin. Typically this is done with a 2

element bias network that consists of a choke and a

DC blocking capacitor. We recommend a ferrite

bead for the main bias choke and quality capacitor

for the DC block. A simple 1 KΩ resistor can be used

as a RF choke for the negative VG as applied to the

input pin.

It is recommended that the total ground (common

mode) inductance not exceed 0.03 nH (30 pH). This

is equivalent to placing at least four 8-mil (200-µm)

diameter vias under the device, assuming an 8-mil

(200-µm) thick RF layer to ground
