Darlington amplifier, with 13.5 dB typical gain and 18
dBm of output power. The input and output are fully
matched to 50 Ω with typical return loss >10 dB.
Third order linearity (OIP3) is typically 28 dBm and
reverse isolation is >21 dB. Functional operation is
achieved with a single bias voltage V
DD
, from +3 V
to +5 V.
An external resistor between V
DD
and pin 6 enables
single bias operation. No negative bias is necessary.
See DC Bias Operation table for external resistor
value selection.
The MAAM-011206 is housed in a leadless 1.5 x 1.2
mm plastic SMT package compatible with standard
pick and place assembly equipment. It is fabricated
using a GaAs process which features full passivation
for increased performance and reliability.
The device is well suited to diverse applications
such as LO drivers, gain blocks and RF driver
stages.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
These electronic devices are sensitive to
electrostatic discharge (ESD) and can be damaged
by static electricity. Proper ESD control techniques
should be used when handling these devices.
6. Exceeding any one or combination of these limits may cause
permanent damage to this device.
7. MACOM does not recommend sustained operation near these
survivability limits.
8. Operating at nominal conditions with T
J
≤ +150°C will ensure
MTTF >1 x 10
6
hours.

Grounding
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.
