Unique Gate Drive Applications Enable Rapidly Switching On/Off for Your High Power Amplifier Question: Can you switch on or off your RF source within 200 ns? Answer: In pulsed radar applications, rapid turn on/off of the high power amplifier (HPA) is required during the transition from transmit to receive operation. Typical transition time objectives can be less than 1 µs. Historically this has been implemented through drain control. Drain control necessitates switching large currents at voltages ranging from 28 V to 50 V. This is practical with known switching power techniques, but involves...
