Often these linear amplifiers are needed when stations want to increase the power being transmitted to the full legal limit as many transceivers, HF, VHF and UHF do not provide this power output level. Linear RF amplifiers are required where signals that have an amplitude component are used. These amplitude components carry information and for this to be accurately preserved, the signal must be amplified in a linear fashion. Signals including amplitude modulation, single sideband, and quadrature amplitude modulation are the main ones and for amateur radio, linear amplifiers are required for single sideband. If the RF amplifier is not linear, then the signal will be distorted and this will result in intermodulation products spreading out either side of the signal to create what is termed splatter. To ensure that no undue levels of splatter are generated so that the minimum amount of interference is caused to other users, it is essential that all additional amplifiers remain linear. Signals that do not carry amplitude variations such as FM signals can use non-linear amplifiers like class C amplifiers which are much more efficient and do not need the same level of heat sink capability etc.
