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. |
