VTP4F, short for Versed Triangle Peak Four Factor Transistor Network, is a specialized network for controlling peak voltage and current in four-channel split-load amplifiers. It is used in applications that require precise peak voltage and power delivery between the four channels. This type of network offers remarkable characteristics compared to other traditional networks, such as long-term stability, excellent peak voltage and current control accuracy, reduced EMI/RFI radiation, and low power dissipation.
VTP4F is a four-factor transistor network that operates over multiple frequency bands, including HF, VHF, UHF, and microwave. It is a combination of five transistors and a differential amplifier with adjustable scaling parameters that allow for wide-range dynamic tuning. This type of network is capable of providing precise peak voltage control on four channels with very low THD, and is suitable for use in applications such as home theater systems, professional audio and video systems, and stereo networks.
The working principle of VTP4F is based on the bridge theory. The bridge is formed by the four transistors at the upstream which form the four-channel split-load amplifier. The 2-input differential amplifier which lies in between the four channels acts as a voltage-controlled amplifier to compensate for the phase differences in signal voltages. The gain of the differential amplifier is determined by the ratio between the voltage-controlled gain (VTG) and the common-mode current (ICM). When the signal is applied to the input of the network, the differential amplifier generates a voltage-controlled voltage (VCT) that is applied to the base of the first transistor. This voltage varies the current drawn by the first transistor, which determines the gain of the network.
The VTP4F also features adjustable scaling parameters, which can be used to fine-tune the VCT of the amplifier and the peak voltage and current levels of each of the four channels. These scaling parameters can be adjusted on-the-fly to suit the application, and can be set to produce any desired power level. The VTP4F can be used in a wide variety of applications, including home theatre systems, professional audio and video systems, controllable power amplifiers, stereo networks, etc.
In summary, VTP4F is a four-factor transistor network that is capable of providing precise peak voltage control on four channels with very low THD. It offers remarkable characteristics such as long-term stability, excellent peak voltage and current control accuracy, reduced EMI/RFI radiation, and low power dissipation. Furthermore, it has adjustable scaling parameters that can be used to fine-tune the peak voltage and current levels of each of the four channels. The VTP4F is ideal for applications that require maximum precision in peak voltage and power delivery between the four channels.
