I have a couple of simple questions relevant a CW ultrasonic doppler. I hope your answers to be helpfully for me.
For a small portable device with USB-Port and operational area from >= 3MHz to <= 10MHz I'm looking for integrated single-channel I/Q-Demodulator with single supply. A like as not the single supply by I/Q-demdulator is not usual.
The AD8333 is a (double) perfect solution for my problem, overall mass with the pin programable phase-shift of outputs is amazing. But I need only the "half" of them and with single supply (<= +5V). The not used I/O's I want connect to the ground. As preamp I want use the AD8337 (or something like that).
Can I use the AD8333 with single supply? I have some ideas, but I'm not sure obout that. For example biasing of the inputs with voltage devider circuits or a HF-Transformer.
But what obout the power supply? Is that a good idea or not? Or what are youre recomendations?
Thank you for your answers.
