Description
The SKY65015 is a general-purpose, broadband amplifier
fabricated from Skyworks InGaP HBT process and packaged in
a plastic Micro-X package. The amplifier’s input and output
impedances are 50 , which allows these amplifiers to be
cascaded without external impedance matching networks. The
typical -3 dB bandwidth of the SKY65015 is DC–3 GHz.
This amplifier is also available in the miniature SC-88 package
(SKY65015-92LF) and the SOT-89 package (SKY65015-70LF)

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, ESD (Electrostatic Discharge) 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.

Description
Equipotential point – Internal circuit com-
mon, which must be connected to the PCB
ground or common via the lowest possible
impedance.
RF input – RF input with 50 nominal
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.
RF output – DC supply voltage input and
RF output with 50 nominal output
impedance. The nominal voltage required
at this pin is listed in the Electrical
Specifications Table. Supply current is
determined by an external resistor
connected between the DC power supply
and this pin.

Output
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, C1 and
C2, to the input and output SMA connectors, respectively.
The positive supply voltage, VS, is connected to pin 3, RF output
of the amplifier via the decoupling network, which consists of C4,
L1, L2 and R1. The power supply current, IS, must be limited,
either via the current limit function of an external bench power
supply, or by replacing L3 with resistor R1, the value of which is
given in the Current Limiting Resistor Values Table. The evaluation
board is shipped with L3 in place, which shifts an in-band series
resonance of the supply decoupling network out of band. For low
frequency applications, R1 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 1 and an identical line
to pin 3. 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
cascade with the output pin of the amplifier.
