Multicarrier Intermodulation products - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Hello,

This is regarding the intermodulation products from Multicarrier transmission. Suppose I have six carriers (1840.6 Mhz,1841.6Mhz,1842.6MHz,1843.6MHz,1844.6 MHz and 1845.6 MHz) spaced 1Mhz apart and fed to a power amplifier.
In this case howmany pure IM3 products will be there?. I did excel calculation and come up with 30 IM3 products(calculated using 2*f2-f1....). Is this correct?
How many IM5 and IM7 products?
Has anybody got excel/matlab for making this type of calculations?
Appreciate your help.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
