Dual-Band CDMA Upconverter
The MRFIC1884 is an integrated upmixer, RF AGC amplifier and driver
amplifier designed for dual鈥揵and, tri鈥搈ode 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鈥檚 RF BiCMOS process and is
packaged in a small cost effective BCC32++ package.
