Application Notes
The RK-35 may be operated at maximum ratings at frequencies up to 60 megacycles. At frequencies between 60 and 120 megacycles, maximum D-C plate voltage should not exceed 1000 volts. Above 120 megacycles, it should not exceed 750 volts. At least 170 volts of fixed bias should be used at 1500V plate for protection.
