Additional Notes

The model 99200 is a triple output sequenced power converter ideally suited for FET RF amplifiers of SSPA’s where output are required to turn on and off in sequence so the negative gate voltage rises first and decays last with respect to the positive outputs.

The 99200 turn-on sequencing feature is controlled by a precision rad hard 100K+ ® MOSFET switches, ensuring reliable operation at FET loads that are enhanced at zero voltage and uncontrolled without negative gate bias.

Turn-off sequencing is achieved by pre-set RC networks, ensuring complete control of the negative gate output as the positive outputs decay first

Other input voltages and output voltage combinations are available.
