Hi. I have a question about the ADRF6614.1. I would like to know the input power range (Min, Max) of REFIN (PIN 43) on the datasheet (Voltage, dbm in two cases). Also, in the description of Pin 43, CMOS is specified. Is it possible to use Sin Wave?2. Mixer is composed of 2 channels. If I only want to use 1 channel, what is the PIN status of unused channel at that time?
For the reference input 0V to 3.3V would be a typical max. If you would like to use a sinusoid at the reference input that is fine.
Two mixer RF inputs are independent of each other. If you would like to use the single channel you don't have to worry about the other one.
