Rigol ATT03301H High Power Attenuator

The Rigol ATT03301H is a fixed 30 dB attenuator designed for high-power RF and microwave applications requiring precise signal level reduction across DC to 3 GHz. It handles 300 W average input power and 5 kW peak power (5 µs pulse), delivering ±0.5 dB typical accuracy while maintaining low VSWR performance. The 50 Ohm impedance and Type N connectors integrate directly into standard test and measurement systems.
