First CDMA Upmixer and Exciter Amplifier
with RF AGC Integrated on a Single Chip
– Higher level of integration cuts digital cellular phone costs
The MRFIC0954 and MRFIC1854 integrate the upmixer and exciter amplifier
functions for dual-band/ dual-mode CDMA cellular phones. These advanced
BiCMOS ICs are the first devices to integrate the upmixer and exciter amplifier with
RF AGC on a single chip. The MRFIC0954 is designed for use at 800 MHz for dual-
mode CDMA/ AMPS phones, while the MRFIC1854 functions at frequencies up to
1.9 GHz for PCS CDMA and Korean band CDMA cellular phones. These two
devices are designed to be used together in dual-band/ dual-mode CDMA phones.
The exciter amplifiers in both ICs incorporate a linear gain control function, and a
selectable bias control pin to reduce power consumption.
Both devices are packaged in a new high power surface mount package, a
special 20-pin TSSOP with a backside metal contact. The package provides excellent
thermal and electrical performance through this solderable metal contact. This large
contact area is physically connected to ground of the MRFIC0954 or MRFIC1854,
and is soldered to the pc board using the same standard reflow process used for
other surface mount components, simplifying the system design and production
processes. The high thermal conductivity of this special TSSOP-20EP package
allows these devices to provide higher RF output power without consuming
excessive board space.
