These values are representative of onboard measurements as defined on the drawing in
paragraph "Evaluation mother board".
(1) _{An external combiner 90° is required on I / Q.}
(2) _{Typical VGL value for IDL = 75mA}
See in paragraph “ biasing option” other possibility to optimise differently the performances
Note: Id is not affected by gain control (GC2, GC3).
