Why is automatic level control (ALC) used with an RF power amplifier?
Pick an answer to check it.
Answer: C. To prevent excessive drive
Automatic level control (ALC) reduces the drive from the transceiver when the amplifier is being pushed too hard. This prevents excessive drive and the distortion and splatter it causes.
Tip: ALC stops overdriving.
