Transistor (HBT) process, which allows for single-supply operation
while maintaining high efficency and good linearity. The device
uses low-cost surface-mount technology (SMT) in the form of a
2.4 x 4.5 mm small outline transistor (SOT-89) package.
The module can operate over a temperature range of –40 °C to
+85 °C. A populated Evaluation Board is available upon request.
A functional block diagram is provided in Figure 1.

DATA SHEET
SKY65009-70LF: LINEAR PA DRIVER
Technical Description
The SKY65009-70LF is a single-stage, wideband PA in a low-cost
surface-mount package. The device operates with a single 3 V or
5 V power supply connected though an RF choke (L1) to the
output pin. Capacitors C7, C8, and C9 provide DC bias decoupling
for VCC.
The bias current is set by the on-chip active bias composed of
current mirror and reference voltage transistors, allowing for
excellent gain tracking over temperature and voltage variations.
The part is externally RF matched using surface mount
components to facilitate operation over a frequency range of
250 MHz to 2500 MHz.
Pin 1 is the RF input and pin 3 is the RF output. External DC
blocking is required for both input and output, but can be
implemented as part of the RF matching circuit. Pin 2 and the
package backside metal, pin 4, provide the DC and RF ground.
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions for the
SKY65009 are provided in Table 1. The absolute maximum
ratings are provided in Table 2, and the recommended operating
conditions in Table 3. Electrical characteristics for the SKY65009
are provided in Table 4.
Typical performance characteristics of the SKY65009 are
illustrated in Figures 2 through 92.
Package and Handling Information
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.
The SKY65009 is rated to Moisture Sensitivity Level 1 (MSL1) at
260
C.
It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
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.

1 Performance is guaranteed only under the conditions listed in the specifications table and is not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty.
ESD HANDLING:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.
