The MRFIC0954 is an integrated upmixer and exciter amplifier designed
specifically for dual–mode CDMA/AMPS digital cellular radios. The exciter
amplifier incorporates a temperature compensated linear gain control. The
design utilizes Motorola’s RF BiCMOS1 process to yield superior
performance in a cost effective monolithic device.
Designed for Dual–Mode Operation
Total Supply Current CDMA Mode = 55 mA Typical
Total Supply Current FM Mode = 35 mA Typical
30 dB Dynamic Range Gain Control on Exciter
Upmixer Output IP3
= 11 dBm Typical
Exciter Output IP3
= 28 dBm Typical
Supply Voltage Range = 2.7 to 3.6 V
Cascaded Adjacent Channel Power (Pout = 6.0 dBm)
@ 885 kHz Offset = –60 dBc Typical
@ 1.98 MHz Offset = –72 dBc Typical
