Note 4:
Input VSWR relative to input impedance in operating mode.
Note 5:
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 6:
Time measured from
SHDN
(MAX2232) low-to-high transition to when output power is within 1dB of final value. Includes
effects of 1% tolerance capacitor.
Note 7:
Time measured from
SHDN
(MAX2232) high-to-low transition to when output power is -20dB of final value. Includes effects
of 1% tolerance capacitors.
Note 8:
Time from die temperature dropping below Thermal Shutdown Temperature, T
