Our Customer measured Logout Voltage & Sloop with Evaluation PCB 124133 HMC662LP3E @8GHz.
Evaluation PCB 124133 setting is default,
J1:SG E83640B (HP/Agilent/Keysight)
J3,J4,J5:E3633 (HP/Agilent/Keysight) 3.3V/84mA,Normal mode.
In the datasheet specification,
LOG OUT & Error vs. Input Power, Fin = 8 GHz
Our Customer measured data is, @8GHz
Logout Voltage & Sloop data is both 1/2.
Other frequency (10,18GHz) also is similar 1/2 characteristics.
What is wrong at customer measurement?
Behavior of Evaluation PCB strange?
Please advise to me.
