LA2-1-1025-33 4886 Integration and Operating Instructions Attach amplifier to heatsink using thin layer of thermal compound. The amplifier will produce approximately 20W of heat, so a medium size heatsink will be adequate - a heatsink with approximate dimensions 2 x the area of the lab amp and approx 1.0” deep. A smaller heatsink may be used if any airflow is used. Attach RF Input and RF Output using SMA Female connectors and tighten. Install ground wire and Vsup using solder connec- tions - m
