... Care should be taken to ensure that all RF traces are 50 Ω. 3. Paths to ground should be made as short as possible. 4. The ground pad of the SKY65038-70LF LNA has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the amplifier ...
