Pi attenuator calculator Formula or Equation
PI attenuator pad is the simple layout pad with provision to solder three RF chip resistors. It is used in RF circuit designs to insert attenuation in the RF path. Depending upon power level requirement at different points in the RF circuit, different PI attenuator values have been chosen. The power level at various points in the RF circuit is chosen based on the 1dB compression points of the devices in the transmit or receive chain. The most popular values of PI attenuator pads are 3dB and 6dB. Following equation or formula is used for PI attenuator resistance values calculation.
Above equation or formula is used for Pi attenuator calculator. As per the equation, different resistor values have been calculated and used in the PI attenuator pad circuit designs.
