Note 1: Minimum and maximum values are guaranteed by design and characterization, not production tested.

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 50

Ω load, while meeting ACPR requirements.

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.
