2. Power amplifier classes - Wikipedia

   en.wikipedia.org/wiki/Power_amplifier_classes

   In electronics, power amplifier classes are letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifier 's characteristics and performance. The first three classes are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a ...

4. RF power amplifier - Wikipedia

   en.wikipedia.org/wiki/RF_power_amplifier

   A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .

5. Bridged and paralleled amplifiers - Wikipedia

   The load is connected between the “hot” (often red) outputs of the two amplifiers, and is subject to the potential difference between them. If the instantaneous potential at the output of one amplifier is at +10 volts, then the output of the other one will be at −10 volts, and the potential difference across the load will be 20 volts, or ...

6. Crossover distortion - Wikipedia

   en.wikipedia.org/wiki/Crossover_distortion

   Crossover distortion is a type of distortion which is caused by switching between devices driving a load. [1] It is most commonly seen in complementary, or "push-pull", class-B amplifier stages, although it is occasionally seen in other types of circuits as well. Input–output characteristic of a class-B complementary emitter follower stage

7. Gain compression - Wikipedia

   en.wikipedia.org/wiki/Gain_compression

   Gain compression is the difference between the ideal linear power transfer curve and the real circuit's power transfer curve. An important gain compression parameter is the OP1dB , which is the power input that results in a 1 dB compression of the output power (OP), corresponding to a gain ratio of 10 - 1 ⁄ 10 = 79.4%.
