Does anyone know some ref of high voltage high bandwidth analog multiplexer? I am looking for a mux that can tolerate input voltages up to 10V, but has also a high bandwidth of at least 1Ghz. I am not sure that such component actually exists...
I need a high bandwidth because I want to pass very short pulses, typically between 1 to 10 ns, in the multiplexer.
Follow-up: I just found parts from Analog that look promising: ADG1236 and ADG1213. Both have a 1 GHz bandwidth and can use a power supply of +/-15V. However the bandwidth is given for a load of 50 ohm. Will the bandwidth heavily depend on the load? In that case, what would be the bandwidth for, say, a load of 1 kohm?
Thanks.
Answer
The ADG1236 and ADG1213 parts from Analog seem to fulfill the requirements. Both have a 1 GHz bandwidth and can use a power supply of +/-15V. They also offer a much higher switching frequency than a relay.
