Description
The SKY67130-396LF is an InGaP HBT linear amplifier driver with
an active bias and superior low-current performance. The
advanced InGaP HBT process provides excellent return loss, low
noise, and high linearity. The internal active bias circuitry provides
stable performance over temperature and process variation.
The supply current can be adjusted, independent of the supply
voltage, using the VBIAS signal (pin 8). The VBIAS pin should be
connected to the control voltage through an external resistor to
control the collector current. The RFIN and RFOUT/VCC pins should
be DC blocked to ensure proper operation.
The SKY67130-396LF is manufactured in a compact, 2 x 2 mm,
8-pin Dual Flat No-Lead (DFN) package. A functional block
diagram is shown in Figure 1. The pin configuration and package
are shown in Figure 2. Signal pin assignments and functional pin
descriptions are provided in Table 1.

Note:
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 value. Exceeding any of the limits listed here may result in permanent damage to the device.
Note 2: Dissipated power is equal to supply voltage (VCC) multiplied by the quiescent current (ICQ).
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 should be used at all times. The
SKY67130-396LF is a Human Body Model (HBM) Class 1A ESD device.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY67130-396LF are
provided in Table 2. Electrical specifications are provided in
Tables 3 and 4.
Typical performance characteristics of the SKY67130-396LF are

Evaluation Board Description
Package and Handling Information
The SKY67130-396LF Evaluation Board is used to test the
performance of the SKY67130-396LF LNA. An assembly drawing
for the Evaluation Board is shown in Figure 28. An Evaluation
Board schematic diagram is provided in Figure 29. Table 5
provides the Bill of Materials (BOM) list for Evaluation Board
2.6 GHz matching components.
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The test board uses a 10 mil Rogers 4350B substrate on a 50 mil
FR4 supporting substrate. The Rogers 4350B material was
selected for the RF circuit because of its low dielectric constant
(εr) and low εr variation over temperature for the best possible
noise performance.
Package Dimensions
THE SKY67130-396LF is rated to Moisture Sensitivity Level 1
(MSL1) at 260 °C. It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
The PCB layout footprint for the SKY67130-396LF is provided in
Figure 30. Typical case markings are shown in Figure 31.
Package dimensions for the 8-pin DFN are shown in Figure 32,
and tape and reel dimensions are provided in Figure 33.
