Description
The SKY65015 is a general-purpose, broadband amplifier fabri-
cated from Skyworks InGaP HBT process and packaged in a
miniature SC-88 package. The amplifier's input and output imped-
ances are 50
, which allows these amplifiers to be cascaded
without external impedance matching networks. The typical -3 dB
bandwidth of the SKY65015 is LF6 GHz.
This amplifier is also available in the plastic micro-X package
(SKY65015-214LF) and the SOT-89 package (SKY65015-70LF).
The SKY65015 is lead (Pb)-free and RoHS compliant.
A populated evaluation board is available upon request.
Full scattering parameters for this part are available for download
at www.skyworksinc.com.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances) compliant packaging.

input impedance. An internally generated
DC voltage is present at this pin, so an
external DC block should be used to
connect this pin to the external circuit.

at this pin is listed in the Electrical

and this pin.
Pin Descriptions
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.
CAUTION: 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. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.

The SKY65015 evaluation board comprises the SKY65015
amplifier, the input and output of which are connected via
50
microstrip transmission lines with DC blocking capacitors,
C
1
and C
2
, to the input and output SMA connectors, respectively.
The positive supply voltage, V
S
, is connected to pin 6, RF Output
of the amplifier via the decoupling network which consists of C
4
,
L
1
, L
2
and R
1
. The power supply current, I
S
, must be limited,
either via the current limit function of an external bench power
supply, or by replacing L
3
with resistor R
1
, the value of which is
given in the Current Limiting Resistor Values table. The evaluation
board is shipped with L
3
in place, which shifts an in-band series
resonance of the supply decoupling network out of band. For low
frequency applications, R
1
may be used to conveniently limit
supply current on the evaluation board.
The evaluation board also contains a probe fixture which
facilitates the direct measurement of the s parameters of the
SKY65015. The probe fixture comprises a very short coplanar
waveguide (CPW) transmission line to pin 3 and an identical line
to pin 6. All other pins of the amplifier are grounded. The CPW
transmission lines are compatible with ground-signal-ground
wafer probe tips, which can be connected to the RF ports of a
vector network analyzer (VNA) via coaxial cables. The very small
electrical length of these CPW transmission lines obviates the
need to de-embed their effects from the s parameters that are
measured. The supply constant current must be applied via the
bias tee, which is typically integrated into the VNA, which is cas-
cade with the output pin of the amplifier.
