Note 1: Minimum and maximum values are guaranteed by design and characterization, not production tested.
Note 2: P
MAX
is met over this frequency range at the ACPR limit with a single matching network. For optimum performance at other
frequencies, the output matching network must be properly designed. See the Applications Information section. Operation
between 750MHz and 1000MHz is possible but has not been characterized.
Note 3: PAE is specified into a 50Ω load, while meeting ACPR requirements.
Note 4: Time from logic transition until P
OUT
is within 1dB of its final mean power.
Note 5: Murata isolator as load with 20:1 VSWR any phase angle after isolator.
Note 6: Noise power can be improved by using the circuit in Figures 1, 2, and 3.
Note 7: Harmonics measured on evaluation kit, which provides some harmonic attenuation in addition to the rejection provided by
the IC. The combined suppression is specified.
Note 8: ≥+25°C guaranteed by production test, ≤+25°C guaranteed through correlation to worst-case temperature testing.
