How to amplify 150,000hz 3.3V 19.38mA DC Square Wave into 20Volt .2A A.C Square Wave Same Frequency.

The discussion focuses on amplifying a 150 kHz, 3.3 V, 19.38 mA DC square wave input into a 20 V, 0.2 A AC square wave output at the same frequency. The AC output is intended to swing between +20 V and -20 V, driving a magnetic inductive coil load with typical small electronics shunt resistance, capacitance, and inductance. Challenges include achieving high frequency operation (150 kHz) with sufficient current and voltage swing, as standard audio amplifiers, motor driver ICs, and power op amps lack the required bandwidth. Proposed solutions involve using a full bridge or H-bridge circuit with optocouplers and complementary high-speed MOSFETs, or a level shifter combined with MOSFET drivers and transistors for efficient and simple implementation. The input waveform rise and fall times should be clean and replicable, with a suggested replacement of the Arduino Due input by a CSS555 timer for waveform generation. Two K3011P optocouplers are available, but suitable complementary MOSFETs need to be identified. The input current measurement was taken with a multimeter, and clarification on exact current and voltage specifications was requested to refine the design approach.
