Description

Skyworks CX65104 Power Amplifier (PA) is a fully matched, 8-pin

Leadless Chip Carrier (LCC) surface mount module, developed for

cellular, Wireless Local Loop (WLL), and Industrial, Scientific,

Medical (ISM) applications. This small, power-efficient PA has a

full 700 to 1000 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 CX65104 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 CX65104. The

device package and pinout are shown in Figure 2. Signal pin

assignments and functional pin descriptions are provided in
