Description
The MAAM-011229 is a broadband high dynamic
range, single stage MMIC LNA assembled in a leadfree 2 mm 8 Lead PDFN plastic package. The
amplifier is internally matched to provide flat gain
and excellent return losses to 3.25 GHz without any
external matching components. Use of external
matching could extend usable frequency range
beyond 4 GHz.
This low noise amplifier has an integrated active
bias circuit allowing direct connection to 3 V or 5 V
bias and minimizing variations over temperature and
process. The bias current can be adjusted with an
optional external resistor, so the user can customize
the power consumption to fit the application. IADJ pin
can be utilized as an enable pin to power the device
up and down during operation.

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.
5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. MACOM does not recommend sustained operation near these
survivability limits.
7. Operating at nominal conditions with TJ ≤ 150°C will ensure
MTTF > 1 x 106 hours.
8. Junction Temperature (TJ) = TC + ӨJC * ((V * I) - (POUT - PIN))
Typical thermal resistance (ӨJC) = 85°C/W
a) For TC = +25°C,
TJ = 59°C @ 5 V, 80 mA
b) For TC = +85°C,
TJ = 119°C @ 5 V, 80 mA

Current Adjust Options
The IADJ (pin 5) of MAAM-011229 may be used to adjust the DC operating current by placing either R1 or R2 as
shown the schematic below. Placing resistor R2 to ground will reduce the current from typical application level.
When using R2 to reduce current do not place (DNP) R1. To increase current from typical application circuit install
resistor R1 and connect to VDD.
The table below shows values of R1 and R2 for a range of operating currents for V DD = 5 V and 3 V.

Applications Section: Power Down Option
The IADJ (pin 5) of MAAM-011229 may be used to power down and turn on the amplifier. The critical
characteristics of the power down circuit are that it presents a low impedance to DC ground in the off mode and
that it presents a high impedance (much greater than 5 kΩ) in the on mode. The single very low cost MMBT3904
NPN switching transistor (available from many suppliers) may be added externally along with a 1 kΩ resistor to
provide this function. As shown in plots below, the time from when voltage on the I ADJ pin (VADJ) goes HIGH to the
time RF reaches 90% of final amplitude is 444 ns. The total turn-on time, however, from change of power down
signal is 1.18 µs (736 ns of this time is consumed in time for MMBT3904 to transition). Alternate choice for
switching transistor could reduce total turn-on time. Total turn off time is 392 ns.
