TRANSMISSION MIXER APPARATUS CAPABLE OF FILTERING

摘要

A transmission mixer apparatus having a filtering function is provided to reduce power consumption by simultaneously performing a filter function and a mixer function and re-using DC current. A transmission mixer apparatus having a filtering function processes current applied from an digital-to-analog converting unit, and includes a filtering/amplifying unit(210), an output amplifying unit(220), and a differential amplifying unit(230). The filtering/amplifying unit(210) filters the current applied from the digital-to-analog converting unit. The output amplifying unit(220) operates by voltage outputted from the filtering/amplifying unit(210), and controls the output of the filtering/amplifying unit(210). The differential amplifying unit(230) transmits power voltage to the output amplifying unit(220).
