Published ratings and characteristics promoted where clearly stated. RFT HT611 metal-ceramic microwave power triode with integral heatsink, for amplifiers, multipliers and oscillators to approximately 6 GHz. Indirectly heated metal-capillary cathode, nominal 6 V at 0.9 A. Maximum plate voltage 600 V, plate dissipation 25 W, cathode current 72 mA and grid dissipation 0.7 W. Typical gm 17 mA/V at plate 400 V and current 60 mA. Heater voltage reduction is recommended for prolonged low-cathode-current dynamic operation.
