Description
The MAAT-010521-L1 is a voltage variable
attenuator with analog control and >30 dB of
attenuation. Excellent linearity is maintained over
the full attenuation range. The attenuation level is
set by two control voltages of 0 to -2 V. This device
is assembled in a lead free 3 mm 16 lead PQFN
plastic package.
Applications include transceivers for cellular
infrastructure.

3. To increase attenuation from minimum attenuation state (VC1 = -2 V and VC2 = -2 V) to maximum attenuation state (VC1 = 0 V and
VC2 = 0 V), VC1 increases to full range prior to adjusting VC2. Typical attenuation measured on MACOM Sample Board in state :
VC1 = 0 V & VC2 = -0.8 V is 20.5 dB for 12.7 - 15.4 GHz band.
4. Guaranteed on MACOM Sample Board only.

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.
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 HBM Class 1A
devices.
