Vacuum tubes can yield impressive amounts of microwave power in small packages, but they must be properly cooled for long-lifetime operation. On that front, the model dB-4150 microwave power module (MPM) developed by dB Control combines a first-stage solid-state amplifier and second-stage traveling-wave-tube (TWT) power booster with effective conductive cooling.
