Marki amplified quadruplers come in two different configurations. One is an amplifier followed by a quadrupler and another amplifier (AQA) and the other is a doubler followed by an amplifier followed by a doubler (DAD). The former offers higher output levels and better suppression of the fundamental while the latter offers better suppressions of the higher order harmonics. As with all multipliers and mixers, it is important to drive amplified quadruplers with the recommended drive level.
