Theory of Operation
The SKY65009-70LF is a single stage, wideband power amplifier
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 V
bias composed of current mirror and reference voltage transis-
tors, allowing for excellent gain tracking over temperature and
voltage variations. The part is externally RF matched using sur-
face mount components to facilitate operation over a frequency
range of 250 to 2500 MHz.
Pin 1 is the RF input and Pin 3 is the RF output. External DC
blocking is required on the input and output, but can be imple-
mented as part of the RF matching circuit. Pin 2 and the package
backside metal, Pin 4, provide the DC and RF ground.
Application Circuit Notes
RF In (Pin 1). Amplifier RF input pin. The amplifier requires a DC
blocking capacitor as part of the external RF matching.
Ground (Pin 2). Attach the ground pin to the RF ground plane
with the largest diameter and lowest inductance via that the
layout will allow. Multiple small vias are also acceptable and will
work well under the device if solder migration is an issue.
RF Out/V
requires a DC blocking capacitor as part of the external RF
matching. The amplifier collector supply voltage is supplied
through an RF choke to the output at pin 3.
Center Ground (Pin 4). It is extremely important that the device
paddle be sufficiently grounded for both thermal and stability rea-
sons. Multiple small vias are acceptable and will work well under
the device if solder migration is an issue.

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 sub-
jected to high temperature during solder assembly.
Please refer to Skyworks solder reflow application note, avail-
able at www.skyworksinc.com, for instructions on mounting the
SKY65009-70LF to a printed circuit board.
Production quantities of this product are shipped in a stan-
dard tape and reel format. For packaging details, refer to the
Skyworks Application Note, Tape and Reel, document number
101568.
Electrostatic Discharge (ESD) Sensitivity
The SKY65009-70LF is a static-sensitive electronic device. Do
not operate or store near strong electrostatic fields. Take proper
ESD precautions.
