CX65003

DATA SHEET CX65003: 1400 – 2500 MHz Linear Power Amplifier Driver Applications PCS/DCS/2.5G/3G base stations Wireless Local Area Networks (WLANs) GSM/CDMA/W-CDMA handsets Wireless Local Loop (WLL) and Industrial, Scientific, Medical (ISM) bands Repeaters Telematics 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.
