Description
Skyworks CX65100 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 CX65100 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 CX65100. The
device package and pinout for the 8-pin Leadless Chip Carrier
(LCC) are shown in Figure 2. Signal pin assignments and
functional pin descriptions are provided in Table 1.
