Description
Skyworks CX65003 power amplifier driver offers a desirable
combination of features that provide superb performance and
ease of use in a low-cost Surface-Mounted Technology (SMT)
package. This Gallium Arsenide (GaAs) Heterojunction Bipolar
Transistor (HBT) power amplifier driver was developed and
optimized for extreme linear performance in a variety of
applications. It is ideal as a driver or output stage in transceivers
and repeaters for Wideband Code Division Multiple Access
(W-CDMA) and CDMA2000 applications.
The 8-pin Small Outline Integrated Circuit (SOIC) device package
and pinout are shown in Figure 1. Figure 2 shows a functional
block diagram for the CX65003. Signal pin assignments and
functional pin descriptions are provided in Table 1.
