• The desired outcome is an ideal limiter
• The linearity of an ideal limiter cannot be
  improved

Predistortion Linearization

• Bottom Line is improvement in Linearity /or
  Efficiency

Improved Linearity at equivalent
Backoff or Operate closer to saturation for
same linearity
Improved Transfer Response
