There is a circuit diagram of the circuit configuration of the optional LO null circuit on page 41 of the data sheet of HMC8191,
but there is no description about the electrical specifications and characteristic examples of bias tee supply.
1. What is the absolute maximum rating of the DC voltage supply for the IF1 / 2 port?
2. We are confused because we do not understand the relevance to the following specifications.
IF Source / Sink Current 3 mA.
The common-mode voltage for each IF port is 0 V.
How should we adjust ? ,and test setup power supply circuit for DC offset ?
