high frequency impedance adaptation

[Ernest Galbrun]

Hello,

I would like to use a PXI-5404 signal generator (I am generating sine waves 10 to 100 MHz) to actuate piezoelectic device. Given the output impedance of the generator, I would need to add an impedance adaptation device to have enough power, can anyone tell me if they know a device (NI or third party) that would do the trick ?

I'd use FETS. Easy and cheap.
