MB54608B Overview
The MB54608L/B is an I/Q Modulator for direct conversion method, and is used for up to 1.0 GHz band digital cellular phones such as GSM, PDC and so on. MB54608L consists of a frequency doubler, a Flip-flop type quadrature phase shifter, I/Q modulator and a mixer for frequency offset with a separate power supply. Fujitsu’s advanced Bipolar process has realized very low current operation(ICC = 16.5 mA @3 V).
