Calculation Formula

IP3 Cascaded = IP3 Amplifier 1 + (IP3 Amplifier 2 - IP3 Amplifier 1) * (Gain Amplifier 2 / Gain Amplifier 1)

Where:
IP3 Cascaded is the third-order intercept point of the cascaded amplifier.
IP3 Amplifier 1 is the third-order intercept point of the first amplifier.
IP3 Amplifier 2 is the third-order intercept point of the second amplifier.
Gain Amplifier 1 is the gain of the first amplifier.
Gain Amplifier 2 is the gain of the second amplifier.

Calculator Description

The Cascaded IP3 Calculator is used to calculate the third-order intercept point (IP3) for cascaded amplifiers. The IP3 is a measure of the linearity of an amplifier and is an important parameter in the design of communication systems.

How to Use

  1. Enter the gain and IP3 values for each amplifier in the cascaded system.
  2. Click the "Calculate" button to compute the cascaded IP3.
  3. The result will be displayed in the "IP3 Cascaded" field.

Formula

The formula used to calculate the cascaded IP3 is:

IP3 Cascaded = IP3 Amplifier 1 + (IP3 Amplifier 2 - IP3 Amplifier 1) * (Gain Amplifier 2 / Gain Amplifier 1)

Principle Explanation

In a cascaded amplifier system, the IP3 of the overall system is influenced by the individual IP3 values and gains of each amplifier. This calculator assumes that the amplifiers are cascaded in a simple series configuration.
