Max. RF Input Limit must be further limited if input VSWR > 2.5:1
Users should avoid exceeding 80% of 2 or more Limits simultaneously
Notes:
•
Operating conditions that exceed the Absolute Maximum Ratings will result in permanent damage to the device.
•
Total Power Dissipation defined as: P
TOT
≡
(P
DC

) – P
OUT
, where:
P

: RF Output Power
•
Total Power Dissipation to be de-rated as follows above 22°C:
P
TOT
= 2.5W – (0.017W/°C) x T
PACK
where T
PACK
=

(coefficient of de-rating formula is the Thermal Conductivity)
Example: For a 65°C source lead temperature: P

= 2.5W – (0.017 x (65 – 22)) = 1.78W

HANDLING PRECAUTIONS
To avoid damage to the devices care should be exercised during handling. Proper Electrostatic
Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and
testing. These devices should be treated as Class 1A per ESD-STM5.1-1998, Human Body Model.
Further information on ESD control measures can be found in MIL-STD-1686 and MIL-HDBK-263.
