5.0V SUPPLy AC ELECTRICAL CHARACTERISTICS (Each Path, Unless Otherwise
Noted)
(Typical Application Circuit, V CC = V CC_AMP_1 = V CC_AMP_2 = V CC_RG = 4.75V to 5.25V, attenuators are set for maximum gain, RF
ports are driven from 50I sources, AMPSET = 0, PD_1 = PD_2 = 0, 100MHz P f RF P 500MHz, T C = -40NC to +85NC. Typical values
are at maximum gain setting, V CC = 5.0V, P IN = -20dBm, f RF = 350MHz, and T C = +25NC, unless otherwise noted.) (Note 6)
