Description

The MB54608B 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.

MB54608B 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). SSOP-20 and BCC-16 package are available.(MB54608L: SSOP-20, MB54608B: BCC-16)
