Order this document by MRFIC1854A/D Advance Information 1.9 GHz CDMA Upmixer/Exciter The MRFIC1854A is an integrated upmixer and exciter amplifier designed specifically for PCS CDMA digital cellular.

Key Features

wer bias current for CDMA at lower powers can be selected via the Bias Select pin. In the high current CDMA mode, the quiescent current is increased to maximize the linearity of the device. In the lower current bias state, the quiescent current is reduced to save current during lower power CDMA operation. The standby mode can be used to reduce current consumption during Voice Activity Factoring. In the standby mode, the LO buffer remains on to prevent VCO pulling and the bandgap reference bias c.
