Selecting RF Microwave Power Amplifiers for EMC Testing

Historically, amplifier selection for Electromagnetic Compatibility (EMC) testing was based mainly on tribal knowledge and information scattered across the EMC industry. However, proper EMC amplifier selection is an important step in achieving required RF levels. It should be noted that quality and support are of equal importance as features when selecting an amplifier. Down-time from equipment failures often means test lab’s throughput slows, thus impacting the lab’s profitability and customer schedules. Additional considerations are numerous. It is important to properly understand the following in order to make a proper decision: Common EMC test standards, Amplifier specification definitions, Types of amplifiers, and other considerations.
