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.

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

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.

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.
