These values are representative of on-board measurements.
(1) _{VD: LO-chain drain bias voltage. VD1: LNA drain bias voltage.}
(2) _{An external combiner 90° is required on I/Q.}
(3) _{ID: LO-chain drain current, typically 125mA.}
(3) _{ID1: LNA drain current, typically 125mA, should be tuned with VGL.}
Electrostatic discharge sensitive device observe handling precautions!
