Question:
(a) what is the negative power supply VEE of the HMC675LC3C. Is there a risk to damage the circuit if the applied voltage higher than -3v e.g. -3.2V
Answer:
(a) The Absolute Maximum Rating (AMR) is -3.15v. It would be preferable to stay within +/-5% tolerance in order to obtained the Optimum performance mentioned in the datasheet. Thus you may consider -3V thus allows a symmetrical signal swing at the input and the output. We don't have any characterization data with Vee=0.
