9 Performance Specification
9.1 Electrical Performance
For a definition of voltage and reference signals, see section 4.1.
9.1.1 Absolute Maximum Ratings
Exceeding these maximum ratings can result in damage to the device.
ESD Warning: This high performance RF integrated circuit is an ESD sensitive device which has
unprotected inputs and outputs. Handling and assembly of this device should only be carried out at an
ESD protected workstation.
