HMC521A how to measure the data about Trace - Deembed Files ,S-parameter

Hi,

The Trace deembed files are not the S Parameters of the device. They are the S Parameters of the traces on the eval board to deembed the loss of the traces.

Thanks,

Taz

Hi Taz - san,

Thank you for reply!

We understood these data as the data including the loss measured at the connector end of the evaluation board.

So there is another question.
The attached file is the data of HMC521 and HMC521A.
The data of HMC521 is described by S1P 1 port data.
On the other hand, HMC521A is described by S2P 2 port data (S11, S12, S21, S22).
What is the difference between these?
What kind of measurement method is used to acquire the S11, S12, S21, and S22 data of the HMC521A, and which data is the 1-port data for each port (RF, LO, IF)?

Best regards

Hi,

Just to reiterate the trace deembed S Parameters are of the HMC521A eval board without the IC. It does not have any information about the performance of the IC.  It is used to deembed the trace and connector loss of the eval board.

Thanks,
