Evaluation Board Description
The SKY66184-11 Evaluation Board is used to test the
performance of the SKY66184-11 PA. A typical application
schematic diagram is shown in Figure 7. A Bill of Materials for the
SKY66184-11 Evaluation Board is listed in Table 6. An assembly
drawing for the Evaluation Board is shown in Figure 8. The board
layer detail is shown in Figure 9. The layer detail physical
characteristics are shown in Figure 10.
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, 2, 6, 11, 13, 15, 16, 20, 21, 25, and 27). 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 work well under the device if solder migration
is an issue.
VBIAS (pin 10). The bias supply voltage for each stage, nominally
set to +3.3 V.
RFOUT (pin 19). Amplifier RF output pin (ZO = 50 Ω). The module
includes an onboard internal DC blocking capacitor. All
impedance matching is provided internal to the module.
VCC1, VCC2, and VCC3 (pins 28, 26, and 23, respectively).
Supply voltage for each stage collector bias is nominally set to
3.3 V. Bypass and decoupling capacitors C1, C2, C3, C4, C5, and
C6 should be placed in the approximate location shown on the
evaluation board assembly drawing, although exact placement is
not critical.
RFIN (pin 4). Amplifier RF input pin (Zo = 50 Ω). The module
includes an onboard internal DC blocking capacitor. All
impedance matching is provided internal to the module.
