Description
The SKY65015 is a general-purpose, broadband amplifier fabricated from Skyworks InGaP HBT process and packaged in a SOT-89 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 LF-6 GHz. This amplifier is also available in the miniature SC-88 package (SKY65015-92LF) and the plastic micro-X package (SKY65015-214LF). The SKY65015 is lead (Pb)-free and RoHS compliant. It is also "Green"--environmentally friendly, containing no antimony or halogens such as bromine. A populated evaluation board is available upon request. Full scattering parameters for this part are available for download at www.skyworksinc.com

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.
Pin Descriptions
Pin Number 2, 4 Pin Name GND Description Equipotential point - Internal circuit common, which must be connected to the PCB ground or common via the lowest possible impedance. Pin 4 must be connected via a low thermal resistance path to a good heatsink. 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.
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 potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times.

Evaluation Board
IS VS C4 L2 L3 R1
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.
