Note 1: Minimum and maximum parameters are guaranteed by design.
Note 2: For optimum performance at a given frequency, output matching network must be designed for maximum output power.
See Applications Information section. Operation outside this frequency range is possible but has not been characterized.
Note 3: No damage to the device.
Note 4: All non-harmonically related outputs are more than 60dB below the desired signal for any electrical phase.
