Evaluation Board

The SKY65017 evaluation board comprises the SKY65017

amplifier, the input and output of which are connected via 50 Ω

The positive supply voltage, V , is connected to pin 3, RF Output

of the amplifier via the decoupling network which consists of C ,

L , L and R . The power supply current, I , must be limited,

either via the current limit function of an external bench power

supply, or by replacing L with resistor R , the value of which is

given in the Current Limiting Resistor Values table. The evaluation

resonance of the supply decoupling network out of band. For low

frequency applications, R may be used to conveniently limit

supply current on the evaluation board.

The evaluation board also contains a probe fixtures which

facilitates the direct measurement of the s parameters of the

SKY65017. 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 cas-

cade with the output pin of the amplifier.

it is recommended to utilize a regulated current source to supply the device under

this condition.
