Notes
Measurements are shown for an unmatched packaged device with the data being de-embedded to the device leads.
The amplifier requires a matching network at the input for proper operation. The amplifier is intrinsically well matched at the output and
ideally should “l(fā)ook” into 50
Ω. Any deviation from this can affect the linearity IP3 performance for the device.
