4. Exceeding any one or combination of these limits may cause
permanent damage to this device.
5. MACOM does not recommend sustained operation near these
survivability limits.
6. Maximum input power is specified with power applied to RF1.
7. Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.

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.

8. C1 is specified as the control for the 16 dB bit. We show
data for the performance with the C2 control - note that the
power handling is reduced if C2 is used for the 16 dB bit.
The electrical performance of the 16 dB bit controlled by
C2 is not specified.
