SUA-45-S1

Universal Heatsink, 45 Watt Power Dissipation Capacity,Uni-Guide™ Compatible
SUA-45-S1 is a universal heatsink, which is designed and fabricated for
SAGE Millimeter’s active device applications with up to 45 watt power
dissipation. The heatsink consists the main heatsink body, a DC fan anda heat spreader. The heat spreader is also known as adapter, which isused to bridge the mounting gap between the heat sink main body andthe to-be-heat-sunk devices, such as power amplifier, frequency active
multiplier, oscillator, transmitter and transceiver due to various mounting
hole locations. The heat spreader offers various mounting patterns toaccommodate more than 15 product models. This heatsink is not only
designed for SAGE Millimeter’s standard products and Uni-Guide™
featured products, but also for many industrial standard microwave andmillimeterwave products offered by other manufacturers. Other heatsinks
with different power dissipation capacities are offered under different
model numbers.

Mounting Instructions:•••Remove the heat spreader from the heatsink by
unscrewing the four provided 2-56x3/16” long mounting
screws.
Mount the heat spreader onto the to-be-heat-sunk device
by inserting 4-40 screws from the slotted surface to form
the sub-assembly. Apply heat compound material between
the two surfaces for better heatsink efficiency.
Remount the sub-assembly onto the heatsink main body.
Apply heat compound material if desired.

NOTE:
•••

On condition that test data is provided it is collected from a sample lot. Actual data may vary slightly from unit to unit. All
testing is performed under +25 °C room temperature.
On condition that simulated test data is provided, actual measured data may slightly vary.
Eravant reserves the right to change the information presented without notice.

CAUTION:•••

If a waveguide is present, any foreign objects in the waveguide will cause performance degradation and may damage ordestroy the unit.
For 1 mm connectors proper torque should be applied: 4.0 ± 0.15 inch-pounds (0.45 ± 0.02 Nm). Torque wrench model
SCH-06004-S1 is highly recommended.
For 1.35 mm, 1.85 mm, 2.4 mm, 2.92 mm, and SMA connectors proper torque should be applied: 8.0 ± 0.15 inch-pounds(0.90 ± 0.02 Nm). Torque wrench model SCH-08008-S1 is highly recommended.
