CX65101
1700 - 2200 MHz Linear Power Amplifier
Conexant鈥檚 CX65101 power amplifier is a fully matched 8-pin Leadless Chip
Carrier (LCC) surface mount module, developed for Personal Communications
System (PCS) and Wireless Local Loop (WLL) applications. This small, power-
efficient amplifier 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). This
device is manufactured with Conexant鈥檚 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 CX65101. The device package
and pinout are shown in Figure 2.
