Hi, all.
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 ?
Best regards,

Hi all,
We've checked the thread linked below, and they're asking questions similar to ours, but they're still unanswered.
Can anyone give us some good advice?

This question is the basic information needed for a customer's circuit design.
We think this design information should be added to the datasheet.
1. Input DC voltage range specififation for IF1,2 ?
We know the following:
However, we do not know how to control the voltage range to limit the current.
Ensure that the source or sink current used for LO suppression is <3 mA for each IF port to
prevent damage to the device.
The common-mode voltage for each IF port is 0 V.
2.Please provide a specific, recommended circuit or ADI test circuit for DC feed to IF1 and IF2.
Best regards,

Hi, The usual applications engineer for this device has recently left ADI. I will try to find the person taking over responsibilities and direct them to this question. Thanks for your patience
