Description
The SKY67111-396LF is GaAs, pHEMT Low-Noise Amplifier (LNA)
with an active bias and high linearity performance. The advanced
GaAs pHEMT enhancement mode process provides excellent
return loss, low noise, and high linearity performance.
The internal active bias circuitry provides stable performance over
temperature and process variation. The device offers the ability to
externally adjust supply current and gain. Supply voltage is
applied to the RFOUT/VDD pin through an RF choke inductor.
Pin 4 (VBIAS) should be connected to RFOUT/VDD through an
external resistor to control the supply current. The RFIN and
RFOUT/VDD pins should be DC blocked to ensure proper
operation. Pin 5 (FEEDBACK) is connected through an RC network
to externally adjust the gain of the device without affecting the
Noise Figure (NF) of the LNA.
The SKY67111-396LF operates in the frequency range of 0.7 to
1.2 GHz with proper tuning.
The LNA 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.

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. The
SKY67111-396LF ESD threshold level is 500 V using Human Body Model (HBM) Class B testing; 30 V using Man-Machine
(MM) Class A testing; and 1000 V using Charged Device Model (CDM) Class IV testing.
Electrical and Mechanical Specifications
Table 4 provides noise source pull information versus frequency.
The absolute maximum ratings of the SKY67111-396LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
Typical performance characteristics of the SKY67111-396LF are
illustrated in Figures 3 through 23.

Evaluation Board Description
Package and Handling Information
The SKY67111-396LF Evaluation Board is used to test the
performance of the SKY67111-396LF LNA. An assembly drawing
for the Evaluation Board is shown in Figure 24. An Evaluation
Board schematic diagram is provided in Figure 25. Table 5
provides the Bill of Materials (BOM) list for Evaluation Board
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 SKY67111-396LF 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 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.
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.
