bias circuit allowing direct connection to 3 V or 5 V
bias and minimizing variations over temperature and
process. The bias current is set by an external
resistor, so the user can customize the power
consumption to fit the application. V
BIAS
can be
utilized as an enable pin to power the device up and
down during operation.
In the 50 Ω environment and at 3 V, the
MAAL-011078 offers 0.5 dB noise figure at 2.6 GHz,
with 22 dB of gain and over 33 dBm output third
order intercept point (OIP3). It is ideal for 4G cellular
infrastructure and Wi-Fi applications.

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.
7. Exceeding any one or combination of these limits may cause
permanent damage to this device.
8. MACOM does not recommend sustained operation near these
survivability limits.
9. Operating at nominal conditions with T

≤ 150°C will ensure
MTTF > 1 x 10

MAAL-011078
Low Noise Amplifier
700 MHz - 6 GHz
Biasing Options
The MAAL-011078 bias can be set in 2 different ways: using only V
DD
or using separate V
DD
and V
BIAS
voltages. A separate V
BIAS
voltage allows pin 5 (V
BIAS
) to be used as an enable pin to power the device up and
down during operation.
For both bias methods select the value of R
BIAS
to achieve the desired current based on the tables on page 4, and
use DC blocks at pin 2 (RF
IN
) and pin 7 (RF
OUT
/ V
DD
).
Rev. V3
Biasing Option - V
DD
only
To use only V
DD
, connect pin 7 (RF
OUT
/ V
DD
) to V
DD
through an RF choke inductor and connect pin 5 (V
BIAS
) to V
DD
through bias resistor R

as shown in Figure 1.
