1.2 Equipment Safety
1.2.1 ESD Precautions
Important
This equipment contains devices which are susceptible to
damage from static charges. You must handle these devices
carefully and according to the procedures described in the
manufacturers’ data books.
We recommend you purchase an antistatic bench kit from a reputable
manufacturer and install and test it according to the manufacturer’s
instructions.
Figure 1.1 shows a typical antistatic bench set-up.
You can obtain further information on antistatic precautions and the dangers
of electrostatic discharge (ESD) from standards such as ANSI/ESD
S20.20-1999 or BS EN 100015-4 1994. The Electrostactic Discharge
Association website is
http://www.esda.org .
1.2.2 Antenna Load
Important
The PA may be damaged if the load is removed or switched
while the PA is transmitting.
To protect the PA output stage from load transients (i.e. switching or
removing the load), we recommend that you fit an isolator between the PA
and the load. Fit the isolator as close as possible to the RF output connector
on the PA. Do not connect any switching or combining equipment
between the isolator and the PA.
