DATA SHEET • SKY65404-31: 5 GHZ LNA
The SKY65404-31 is matched at the RF output port (pin 4) and
requires only a shunt capacitor match at the RF input port (pin 3).
The VCC signal (pin 6) requires a simple bypass circuit. An
external resistor on the V_ENABLE signal (pin 1) allows a wide
range of control voltages to be used. Shutdown mode is achieved
by switching the V_ENABLE signal to 0 V.
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 SKY65404-31 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.
