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
IN
) – P
OUT
, where:
P
DC
: DC Bias Power
P
IN
: RF Input Power
P
OUT
: RF Output Power
Total Power Dissipation to be de-rated as follows above 22
°
C:
P
TOT
= 1.4 - (0.004W/
°
C) x T
CARRIER
where T
CARRIER
=
carrier or heatsink temperature above 22
°
C
(coefficient of de-rating formula is the Thermal Conductivity)
Example: For a 55
°
C carrier temperature: P
TOT
= 1.4 - (0.004 x (55 – 22)) = 1.26W
For optimum heatsinking eutectic die attach is recommended; conductive epoxy die attach is acceptable with
some degradation in thermal de-rating performance (P
TOT
= 550mW)
Note on Thermal Resistivity:
The nominal value of 250
°
C/W is stated for the input stage, which will reach
temperature limits before the output stage. The aggregate MMIC thermal resistivity is approximately 80
°
C/W.
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.
