🔍 Key Concepts

• Modern marine RADAR power supply design (solid-state vs older designs) • Differences between high-voltage magnetron supply and low-voltage system supply • Typical nature of low-voltage outputs in electronics (AC vs DC, single vs multiple voltages)

💭 Think About

• For each choice, ask yourself: does this match what you would expect inside any modern electronic device (like a computer or GPS), or does it sound unusual? • Think about what the magnetron (the RADAR transmitter tube) needs versus what the rest of the RADAR set (display, controls, processors) needs. • Which statement describes something that would be least likely or least practical in a compact, efficient, modern marine RADAR power supply?

✅ Before You Answer

• Recall that magnetrons require very high DC voltage—how is that usually created from the ship's power? • Consider whether low-voltage circuits in modern electronics are usually AC, DC, or a mix, and how many different voltage levels they commonly provide. • Check which statement conflicts with what you know about switch-mode power supplies (SMPS) used in modern electronics.
