Layout Guidelines

To achieve the levels of high-frequency performance of the THS2630, follow proper printed-circuit board (PCB) high-frequency design techniques. Following is a general set of guidelines. In addition, a SLOU554 is available to use as a guide for layout or for evaluating device performance.

  • Ground planes—Use a ground plane on the board to provide all components with a low inductive ground connection. However, in the areas of the amplifier inputs and output, the ground plane can be removed to minimize the stray capacitance.
  • Proper power-supply decoupling—use a 6.8-µF tantalum capacitor in parallel with a 0.1-µF ceramic capacitor on each supply pin. Sharing the tantalum among several amplifiers is possible depending on the application; however, always use a 0.1-µF ceramic capacitor on the supply pin of every amplifier. In addition, place the 0.1-µF capacitor as close as possible to the supply pin. As this distance increases, the inductance in the connecting trace makes the capacitor less effective. Strive for distances of less than 0.1 inches between the device power pin and the ceramic capacitors.
  • Short trace runs or compact part placements—to optimize high-frequency performance, minimize stray series inductance. The best method is to make the circuit layout as compact as possible, thereby minimizing the length of all trace runs. Pay particular attention to the inputs of the amplifier; keep the length as short as possible. This short length helps minimize stray capacitance at the input of the amplifier.
