1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set
at or below their nominal values. Exceeding any of the limits listed here may result in permanent damage to the device.
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.

DATA SHEET • SKY65017-70LF: CASCADABLE AMPLIFIER
Evaluation Board Description
The Skyworks SKY65017-70LF Evaluation Board is used to test
the performance of the SKY65017-70LF cascadable amplifier.
The Evaluation Board is shown in Figure 7. An Evaluation Board
schematic is shown in Figure 8. Table 4 provides the Bill of
Materials (BOM) for Evaluation Board components.
The input and output of the SKY65017-70LF are connected using
50 Ω microstrip transmission lines with DC blocking capacitors,
C1 and C2, to the input and output SMA connectors, respectively.
The positive supply voltage, VCC, is connected to pin 3 (OUTPUT)
of the amplifier using the decoupling network that consists of C4,
L1, L2, and R1. The power supply current, IDD, must be limited
either by the current limit function of an external bench power
supply or by replacing L3 with resistor R1, the value of which is
given in shown in Table 5.
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 that facilitates
the direct measurement of the S-parameters. The probe fixture
comprises a very short Co-Planar Waveguide (CPW) transmission
line to pin 1 and an identical line to pin 3. The other two 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) using 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 using the bias tee, which is typically integrated
into the VNA, and cascaded with the OUTPUT pin of the amplifier.
