These values are representative of onboard measurements as defined on the drawing in
paragraph "Evaluation mother board".
(1) _{VD1: 1}st _{stage LNA drain bias voltage. VD2: 2}nd _{stage LNA drain bias voltage.}
(1) _{VD3: LO-chain drain bias voltage.}
(2) _{An external combiner 90° is required on I / Q.}
(3) _{ID1: 1}st _{stage LNA drain current, typically 14mA, should be tuned with VG1.}
(3) _{ID2: 2}nd _{stage LNA drain current, typically 31mA, should be tuned with VG2.}
(3) _{ID3: LO-chain drain current, typically 35mA, should be tuned with VG3.}
Electrostatic discharge sensitive device observe handling precautions!
