6.1 The Gain of the CC2592

Changing the layout or the stack-up of the reference design affects the RF performance of the CC2592. Due to all the contributors to the CC2592 performance, a few observations can be made on how changing layout and PCB stack-up affects the amplifier:

  • Bad soldering of the ground paddle can reduce the gain significantly.
  • Too few or too long vias reduce the gain significantly. Because of this, a checkered pattern of vias and solder paste, and a 4-layer PCB with the ground plane close to the top layer was chosen for the SimpleLink™ ZigBee® Network Range Extender Reference Design[3].
