The external bypass capacitors, C1 and C2, provide additional high frequency bypassing at the amplifier power pins. The C3, C4, C5, and C6 capacitors provide additional board level bypassing. The VCC layer is sandwiched with the GND layer to provide mechanical stability and distributed interplanar capacitance between VCC and GND. The bottom three layers sandwich the VEE plane layers between two GND layers, generating distributed interplanar capacitance. 50 IMPEDANCE EVALUATION BOARD STACK UP TOP COPPER - SIGNAL GND VCC SPACING GND VEE BOTTOM COPPER - GND Figure 8. Stack Up Rev. 0 | Page 5 of 6 14072-008 This 6-layer FR4 board design provides optimized high speed and low noise performance. The first ground layer is spaced to provide a 50 controlled impedance with the primary layer to optimize high frequency performance.
