te: Exceeding one or more of the limiting values may cause permanent damage to the module.
Notes and Cautions:
Design Notes
(1) It is critical to following the recommendations of this document to ensure the module meets the
specifications.
(2) Power supply must be free of AC ripple voltage. If such noise is present, it is critical to provide proper
filtering and decoupling.
(3) The module should not be stressed mechanically after installation.
(4) Exposing the module to significant temperatures will result in degradation and decreased lifetime.
(5) Keep module away from other high frequency devices which may interfere with operation such as
other transmitters and devices generating high frequencies.
(6) Avoid static electricity, ESD and high voltage as these may damage the module.
Handling and Storage
(1) Keep module away from other high frequency devices which may interfere with operation such as
other transmitters and devices generating high frequencies.
(2) Do not expose the module to the following conditions: Corrosive gasses such as Cl2, H2S, NH3, SO2,
or NOX Extreme humidity or salty air Prolonged exposure to direct Sunlight Temperatures beyond those
specified for storage.
(3) Do not apply mechanical stress.
(4) Do not drop or shock the module.
(5) Avoid static electricity, ESD and high voltage as these may damage the module.
