I have a question regarding the mixer. Currently, i design a mixer and going to tape out soon. My mixer is operated at 2.4 GHz and output frequency is 3 MHz and i need connect the mixer to a buffer for measurement purpose. Do i need a 50 ohm impedance matching for the output buffer? Because as i know, for low frequency (3MHz), it is not require impedance matching at the output. I thinking of should i have this output 50 ohm for the buffer. Appreciate if can help me to clear this doubt. Thank you very much.
