AC ELECTRICAL CHARACTERISTICS
( Typical Application Circuit with analog attenuator set for maximum gain, V CC = 4.75V to 5.8V, f RF = 1835MHz, P RFIN = -16dBm
(CW), T C = -40°C to +95°C, and RF ports are connected to 50? sources and loads, unless otherwise noted. Typical values are at
T C = +25°C, V CC = 5.5V, P RF_IN = -16dBm, V PLVLSET = 2.5V, CTRL1 = 1, CTRL2 = 0. Min/max specifications apply over supply,
process, and temperature, unless otherwise noted.) (Notes 5, 7)
