with analog control and up to 40 dB of attenuation.
Excellent linearity is maintained over the full
attenuation range. The attenuation level is set by
two control voltages of 0 to -2V.
The 3mm QFN package is RoHS compliant and
compatible with reflow temperatures to 260°C.
Applications include transceivers for cellular
infrastructure.

5. To increase attenuation from minimum attenuation state (VC1 = -2 V and VC2 = -2 V) to max attenuation state (VC1 = 0 V and VC2 = 0 V),
VC1 increases to full range prior to adjusting VC2.

Handling Procedures
The following precautions should be observed 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 class 1C
(HBM) 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.
