Dual-Band CDMA Upconverter
The MRFIC1884 is an integrated upmixer, RF AGC amplifier and driver amplifier designed for dual-band, tri-mode CDMA/AMPS/PCS CDMA cellular radios. The device incorporates a temperature compensated linear gain control and an active bias control that reduces supply current at lower output power. The design utilizes Motorola's RF BiCMOS process and is packaged in a small cost effective BCC32++ package.
