Description
Skyworks CX65105 Power Amplifier (PA) is a fully matched, 8-pin
Leadless Chip Carrier (LCC) surface mount module, developed for
Personal Communications System (PCS), Digital Communications
System (DCS), and Universal Mobile Telephone System (UMTS)
applications. Wireless Local Loop (WLL) and Industrial, Scientific,
Medical (ISM) applications are also supported.
This small, power-efficient PA has a full 1700 to 2200 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 CX65105 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.
The 8-pin Leadless Chip Carrier (LCC) device package and pinout
are shown in Figure 1. Figure 2 shows a functional block diagram
for the CX65105. Signal pin assignments and functional pin
descriptions are provided in Table 1.
