Abstract

Intermodulation (IM) and harmonic products are caused by non-linear mixing of signals at the RF stages of radio systems. Interference due to IM and harmonic products is usually of concern especially where antennas are located in close vicinity. This paper deals with IM and harmonic products of two and three impinging signals. Interference analysis are presented for: two-signal third-order IM, two-signal fifth-order IM, three-signal third-order IM, three-signal fifth-order IM, as well as second-order and third-order harmonics. The capabilities of the assignment and licensing systems (ALS) have been extended to handle harmonics and IM products up to three-signal fifth-order. Examples of IM conflicts in the land mobile frequency bands are presented
