DESCRIPTION
Skyworks' SKY65004 is a high performance, ultra-wideband
amplifier with superior output power, linearity and efficiency.
The device is fabricated using Skyworks high reliability
Aluminum Gallium Arsenide (AlGaAs) Heterojunction Bipolar
Transistor (HBT) technology. The device uses low-cost
Surface-Mount Technology (SMT) in the form of a Small
Outline Transistor (SOT) package, which allows for a highly
manufacturable low cost solution.
The high linearity and superior Adjacent Channel Power
Rejection/Adjacent Channel Leakage Power Ratio (ACPR/ACLR)
performance of the SKY65004 make it ideal for use in the
driver stage of infrastucture transmit chains.
The device package and pinout for the 4-pin SOT-89 package
are shown in Figure 1. Figure 2 shows a functional block
diagram for the SKY65004.

Electrical and Mechanical Specifications
The signal pin assignments and functions are described in
Table 1. The absolute maximum ratings of the SKY65004 are
provided in Table 2. The recommended operating conditions
are specified in Table 3 and electrical specifications are
provided in Table 4.
Figures 3 through 15 illustrate the device performance in
various operating bands. Figure 16 provides the package
dimensions for the 4-pin SOT-89 device.
Electrostatic Discharge (ESD) Sensitivity
The SKY65004 is a static-sensitive electronic device. Do not
operate or store near strong electrostatic fields. Take proper
ESD precautions.
