I am working with MEMS structures and need to move a device (switch) in a operating point with quite high offset. (150V DC offset and a voltage swing of 60V) To generate the high HF Voltage (up to 5MHz) we use a System WMA-300 from Falco Systems.
In the end I want to record a response function of the device depending on the frequency (between 1Hz ideally (but 5kHz is fine) and 5 MHz) of the driving signal (between 120V and 180V). The signal that needs to arrive at the MEMS device should look as follows (Sorry for the badly drawn chirped sine).
When thinking about the solution, I was mainly afraid that somebody would operate the system wrongly applying a low frequency signal to the input coil thereby burning the primary coil. (50 Ohm source impedance, and 0.3Ohm coil resistance) Do I need to prevent this by adding a High-Pass filter in front of the primary coil?
Is there a better idea how to create this signal?
There is a better way to do it (see the accepted answer), seems the transformer is overkill.
