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?
