    Class B Amplifier and the Class-B Transistor Amplifier
    A push-pull amplifier module is a circuit configuration utilizing a complementary pair of transistors (typically NPN and PNP) to alternately "push" (source) and "pull" (sink) current into a load, commonly used to improve efficiency and reduce distortion in audio and RF power applications. These modules, often designed in Class B or AB, significantly enhance output power compared to single-ended designs by having each transistor handle half of the signal cycle.

    Key Characteristics and Components 
    • Complementary Transistors: Utilizes NPN/PNP pairs to handle the positive and negative halves of a signal, respectively.
    • Efficiency: Class B push-pull amplifiers are highly efficient, as they dissipate little power when no signal is present.
    • Reduced Distortion: The configuration eliminates even-order harmonics and, when using Class AB biasing, minimizes crossover distortion (the "dead zone" at zero crossing).
    • Applications: Common in audio power amplifiers, CATV systems, and RF signal amplification.

    Common Types 
    • Class B Push-Pull: Transistors are off until the signal arrives; highly efficient but susceptible to crossover distortion.
    • Class AB Push-Pull: Transistors are lightly biased to stay just on, eliminating crossover distortion.
    • Transformer-Coupled: Uses input and output transformers for impedance matching and phase inversion, particularly in audio.
    • Complementary-Symmetry: Uses matched NPN/PNP transistors without transformers, common in modern IC designs. 
    Typical Specifications (e.g., RF/CATV Module) 
    • Frequency Range: Frequently designed for high-frequency applications (e.g., 40-550 MHz or higher).
    • Gain: High-gain options are available, often 30dB+.
    • Power Supply: Usually operates on DC voltage, such as 24V.
    • Performance: High linearity and low noise. 
    Examples of push-pull amplifier components include the 2N3904 (NPN) and 2N3906 (PNP) pairs for low-power stages, while pre-built modules are available for RF applications, such as the Qorvo QPA3358 from Mouser.
