Application Circuit Notes
Center Ground. It is extremely important to sufficiently ground
the bottom ground pad of the device for both thermal and stability
reasons. Multiple small vias are acceptable and work well under
the device if solder migration is an issue.
GND (pins 1, 3, 4, 7, 8, 10, 11, 13, and 15). Attach all ground
pins to the RF ground plane with the largest diameter and lowest
inductance via that the layout allows. Multiple small vias are
acceptable and will work well under the device if solder migration
is an issue.
VBIAS (pin 5). The bias supply voltage for each stage, nominally
set to +5 V.
RFOUT (pin 9). Amplifier RF output pin (ZO = 50 ). The module
includes an internal DC blocking capacitor. All impedance
matching is provided internal to the module.
VCC1, VCC2, and VCC3 (pin 16, 14, and 12, respectively). Supply
voltage for each stage collector bias is nominally set to 5 V. The
evaluation board has inductors L1 and L2. These are place
holders, and should be populated with 0  resistors. Bypass and
decoupling capacitors C6 through C12 should be placed in the
approximate location shown on the evaluation board assembly
drawing, although exact placement is not critical.
RFIN (pin 2). Amplifier RF input pin (ZO = 50 ). All impedance
matching is provided internally to the module.
Package Dimensions
Typical part marking for the SKY66293-21 is shown in
Figure 21.The PCB layout footprint for the SKY66293-21 is shown
in Figure 22. Package dimensions are shown in Figure 23, and
tape and reel dimensions are provided in Figure 24.
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 SKY66293-21 is rated to Moisture Sensitivity Level 3 (MSL3)
at 250 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.
