... V SHDN Note 4: Harmonics are measured on the MAX2251 EV kit. The output matching provides some harmonic attenuation in addition to the rejection provided by the IC. The combined suppression is specified. Note 5: The range is defined by the difference between the rated linear output power and the output power that corresponds ...
