The RF2157 is a high-power, high-efficiency linear ampli-
fier IC targeting 3V handheld systems. The device is
manufactured on an advanced Gallium Arsenide Hetero-
junction Bipolar Transistor (HBT) process, and has been
designed for use as the final RF amplifier in dual-mode
3V CDMA and TDMA handheld digital equipment,
spread-spectrum systems, and other applications in the
1710MHz to 1910MHz band. The device is packaged in a
compact 4mmx4mm LCC, as well as a 4mmx4mm MLF
(micro leaded package). The frequency response can be
optimized for linear performance over 1710MHz to
1910MHz. The device features a digital mode switch
which can be used to minimize operating current under
low output power conditions.
