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.
• Designed for Dual–Band, Tri–Mode Operation
Total Supply Current CDMA/PCS CDMA Mode = 60 mA (Typ)
Total Supply Current AMPS Mode = 42 mA (Typ)
• High Output Power
6.0 dBm for CDMA
6.0 dBm for PCS CDMA
11 dBm for AMPS
• Supply Voltage Range: 2.7 to 3.2 V
