Actually, you need to give switching times, or slew rates. A 1Mhz 200V P-P sine wave would meet the requirements you've give so far. You are hinting at digital signals, but without the digital specs.
There are a lot of ways to do this, the more important consideration is probably how the printed circuit board is laid out, since parasitics are going to be the big problem.
What kind of load, for example? This is critical no matter if it is digital or analog. Load is expressed in ohm's in this case.
You are not going to get any kind of meaningful answers unless you give meaningful information as to what the requirements are.
One last comment, you have not mentioned what country this is being done in. 1 Mhz is in the middle of a commercial band of signals, pretty much international as far as I know. If you broadcast and jam these signals (200V is a lot of potential power) you are going to have the authorities down on your necks. I've seen a lot of people (especially from India) poh poh this, but it is an international requirement.
Are you looking for a schematic with the component(s) selected? Do you need to switch from the ground end or the -200v end? Do you care about the rise and fall time of the signal? Is the load purely resistive or reactive? I would use a MOSFET to switch, but the choice of exactly which one depends on your answers to the above questions. 1 volt would not switch the gate directly, as already stated, you will need additional amplification to raise the 1 volt pulse to at least 5 volts, and would like it in the 10 - 12 volt range. But depending on whether you are switching on the ground side or the -200 v side, you might have to shift the amplified drive signal down to switch between -190 v and -200 or so. Easily done with another transistor or so, but again how depends on exactly what you are trying to switch.
It seems like you think this is quite simple. And it is just for us whip something up. Electronics of this kind is not easy. If you want any help from us you have to put in some effort by your self. As a start go back to list posted by Bill M. And at least try to give some answers to the question he is asking D'oh!.It's not for you sir...
