Description
The SKY65374-11 is variable gain Low-Noise Amplifier (LNA) with
an active bias and high linearity performance. The first stage of
the device is comprised of an LNA with a bypass switch that is
followed by a high linearity driver amplifier, a variable voltage
attenuator, and a high linearity power amplifier. This module
architecture provides excellent return loss, low noise, and high
linearity performance.

The internal active bias circuitry ensures repeatable performance
over temperature. The device is fully integrated and requires
minimal external components.
The SKY65374-11 is manufactured in a compact, 8 x 8 mm,
16-pin Multi-Chip Module (MCM) 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.

Package and Handling Information
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed before shipping. 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 SKY65374-11is rated to Moisture Sensitivity Level 3 (MSL3)
at 260 °C. It can be used for lead or lead-free soldering. For
additional information, refer to Skyworks Application Note, PCB
Design and SMT Assembly/Rework Guidelines for MCM-L
Packages, document number 101752.
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.
