T
Note 1: ≥ +25°C guaranteed by production test, <+25°C guaranteed by design and characterization.
Note 2: MAX guaranteed by production test, MIN guaranteed by design and characterization.
Note 3: Guaranteed by design and characterization.
Note 4: For optimum performance at a given frequency, design the output matching network for maximum output power.
Note 5: Gain is monotonic with V
Note 6: 0.068µF capacitor from RAMP to REF. Time is measured from SHDN low-to-high transition to +29dBm output power, or
Note 7: Harmonics measured on the evaluation kit, which provides some harmonic attenuation in addition to the rejection provided
