More informations
Here are listed some transistors particularly suitable for class A ultralinear applications:
- To amplify the TV signal in AM or with digital modulation with high linearity devices particularly suitable for this purpose.
- Broadband power amplifiers suitable for electromagnetic compatibility tests, for this porpose too are required class A linear transistors.
- Final stage of RF generators, final transistors of TV broadband switchboards when it is required a considerable linearity, low intermodulation and resistance to strong signals, broad band or narrow band stages for laboratory use etc…
Warning: The following power values are referred to A class TV usage.
These transistors are also listed also on other categories as they are specified for other use than class A, for the same device characteristics of gain, efficiency and output power are significantly reduced in class A for the benefit of a much higher linearity.
Class A output level is measured with intermodulation IMD @ -58 / -60 dB (CCIR rules) or -54 / -58 dB for ≥ 1 W devices, dBmV = signal level in dB over 1 mV.
