TYPES OF APPLICATIONS
These integrated upmixers/ exciters with on-chip gain and bias controls are
ideal for use in dual-band/ dual-mode CDMA cellular phones that operate in the
800 MHz and 1.9 GHz bands.
The MRFIC0954 800 MHz Integrated Upmixer and Exciter Amplifier
is designed specifically for use in CDMA and AMPS cellular phones.
The MRFIC1854 1.9 GHz Upmixer/ Exciter will find application in 1.9 GHz
Personal Communication Systems (PCS) CDMA and Korean CDMA digital
cellular phones.
Both of these devices are designed to be used together in dual-band/ dual-
mode CDMA phones.
