Hi Support Group,
May I know the power loss of the connector at the output of EVAL01-HMC6981LS6.
Hello Hai Poh Lee,
For RF/microwave coaxial connectors, EVAL01-HMC6981LS6 uses SRI Connector Gage Company part # 25-146-1000-92. See link below:
With this EVAL board we don't usually consider component quantities such as your stated "power loss of the connector at the output", but instead measure the S-parameters of the entire THRU CAL structure to obtain the non-DUT losses (including connectors). From there, the DUT power measured out of the J2 connector can be corrected by adding to it 1/2 of the THRU CAL S21 magnitude, while the DUT gain measured from J1 to J2 can be corrected by adding in the THRU CAL S21 magnitude. For your convenience, I've attached the S-parameters we measured for the THRU CAL structure.
This method provide fairly accurate correction of the scalar quantities measured, helping you to shift the gain and power reference planes from the connectors to the DUT pins.
I couldn't find the attached S-Parameters.
Hai, you have to view the post on EngineerZone to see the attachment.
