Description
Skyworks SKY65119 Power Amplifier (PA) is a fully matched, 12-pin lead-free Multi-Chip Module (MCM) developed for cellular, Wireless Local Loop (WLL), and Industrial, Scientific, Medical (ISM) applications. This small, power-efficient PA has a full 700 to 800 MHz bandwidth coverage packed into a single compact package. All active circuitry in the module is contained in a single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC). The SKY65119 is manufactured with Skyworks Aluminum (Al) GaAs Heterojunction Bipolar
Transistor (HBT) process, which allows for single supply operation while maintaining high efficiency and good linearity. Figure 1 shows a functional block diagram for the SKY65119. The device package and pinout are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.
