The SKY67015-396LF is a GaAs, pHEMT low-noise amplifier
(LNA) with an integrated active bias. The advanced GaAs pHEMT
enhancement mode process provides excellent return loss, low
noise, and high linearity.
The SKY67015-396LF is typically used at frequencies ranging
from 100 MHz to 300 MHz, The device has been successfully
tuned down to 30 MHz with the addition of external RC feedback.
Please contact Skyworks for details.
The device offers the ability to externally adjust the supply
current. The supply voltage is applied to the RF-OUT/VDD pin
through an RF choke inductor. The VBIAS pin should be connected
to the RF_OUT/VDD pin through an external resistor to control the
supply current. Both RF_OUT/VDD and RF_IN pins should be DC
blocked to ensure proper operation.
The SKY67015-396LF 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 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 value. Exceeding any of the limits listed here may result in permanent damage to the device.
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.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY67015-396LF are
provided in Table 2. Electrical specifications are provided in
Tables 3 (18 mA operation) and 4 (5 mA operation).
Typical performance characteristics of the SKY67015-396LF are
illustrated in Figures 3 through 15.

when the part is subjected to high temperature during solder
assembly.
Package Dimensions
The SKY67015-396LF 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.
The PCB layout footprint for the SKY67015-396LF is provided in
Figure 18. Typical case markings are shown in Figure 19.
Package dimensions for the 8-pin DFN are shown in Figure 20,
and tape and reel dimensions are provided in Figure 21.
