Electrical Characteristics

(both bands), I, Q input = 1.4 volts p.p, test frequency = 849MHz (900 output) and 1910MHz (1900

output).These characteristics are guaranteed by either production test or design. They apply within the

specified ambient temperature and supply voltage ranges unless otherwise stated.
