CX65104: 700 – 1000 MHz Linear Power Amplifier
Applications
• AMPS/CDMA/TDMA/GSM • Repeaters • WLL and ISM bands • Mobile radio • Paging • Telematics
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 Table 1.

Technical Description
The CX65104 is comprised of two amplifier stages. The matching circuits for the input stage, inter-stage, and output stage are contained within the device. The bias circuits for both input and output stages are included within the device for optimum temperature tracking performance. The CX65104 is internally matched for optimum linearity and efficiency. The input and output stages are independently supplied using the VCC1 and VCC2 supply lines, pins 8 and 4 respectively.
ensure that the part is not subjected to a temperature that exceeds 300 °C for more than 10 seconds. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. Production quantities of this product are shipped in a standard tape and reel format. For packaging details, refer to the Skyworks Application Note, Tape and Reel, document number 101568.
Electrical and Mechanical Specifications
The absolute maximum ratings of the CX65104 are provided in Table 2. The recommended operating conditions are specified in Table 3 and electrical specifications are provided in Table 4. Typical performance characteristics over temperature of the CX65104 are illustrated in Figures 3 through 8. Figure 9 shows the package dimensions for the 8-pin CX65104 LCC and Figure 10 provides the tape and reel dimensions.
Package and Handling Information
Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. If the part is attached in a reflow oven, the temperature ramp rate should not exceed 5 °C per second. Maximum temperature should not exceed 225 °C and the time spent at a temperature that exceeds 210 °C should be limited to less than 10 seconds. If the part is manually attached, precaution should be taken to
Electrostatic Discharge (ESD) Sensitivity
The CX65104 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper ESD precautions.
