RF Intermodulation Calculator
Calculate potential intermodulation products generated by multiple transmitter frequencies and identify products that fall within specified receiver frequencies.
Enter the transmitter and receiver frequencies, select the number of transmitter frequencies to evaluate at a time, and specify the maximum intermodulation order to calculate.
Engineering Notes
Intermodulation products are unwanted frequencies that can be generated when multiple transmitter signals are present in the same RF environment. The calculator generates intermodulation products from the specified transmitter frequencies and checks them against the receiver frequencies entered by the user.
The number of transmitter frequencies evaluated together and the maximum intermodulation order can be adjusted using the calculator options. For larger transmitter lists, use smaller groups and lower intermodulation orders to keep the calculation manageable.
FAQ
What is this calculator used for?
It calculates potential intermodulation products generated by combinations of transmitter frequencies and checks whether those products occur near specified receiver frequencies.
Why do I need to enter both Tx and Rx frequencies?
The Tx frequencies are used to generate the intermodulation products. The Rx frequencies are used to determine whether calculated products may fall within the receiver frequencies being evaluated.
Why should I use fewer transmitters for higher-order calculations?
The number of possible intermodulation combinations increases rapidly as the number of transmitter frequencies and the intermodulation order increase. For large transmitter lists, evaluate smaller groups at a time.
