VMK90-02T2 Application Field and Working Principle

The VMK90-02T2 is a series of transistor arrays (TAs) produced by Vishay Semiconductors. These TAs are low-voltage, low-power field-effect transistors (FETs) arranged in an integrated circuit (IC). This series comprises four TAs of different types: VMK90-02T3-K, VMK90-02T3, VMK90-02T2-K, and VMK90-02T2. All four TAs have different performance parameters and are used in different applications.

The VMK90-02T2 TA is composed of p-channel and n-channel metal-oxide-semiconductor field-effect transistors (MOSFETs). These transistors are suitable for working with both types of power supplies, for example, positive and negative. Compared with other transistors, this TA has a better switching speed and higher power efficiency, making it a better choice in some applications.

The VMK90-02T2 is designed for switching and amplifying applications, primarily in the telecommunications and audio/video industry. It is particularly suitable for crossovers and high-speed audio amplifiers. The circuit reduces the device\'s input capacitance, resulting in better power performance. This exceeds the characteristics of traditional STAs and helps reduce size and power consumption.

The VMK90-02T2 TA can be used in a variety of applications, including voltage regulation, communications, electronics, and automotive applications. It is used in automotive audio systems to control high power systems with low power transistors. It is also used in communications to ensure the performance of transmission and reception communication systems.

The main feature of the VMK90-02T2 is its high speed performance. It has a maximum operating frequency of 175MHz, making it significantly faster than other transistors. This high-speed performance is the result of its low input capacitance and high frequency current switching ability. The high-frequency output power is also greater than that of other transistors in this TA series.

The working principle of the VMK90-02T2 lies in its ability to provide a high-frequency output power at low voltage and low power. The output current is controlled by the gate-to-source voltage and the gate-to-drain voltage. When the gate-to-source voltage is low, the gate-to-drain voltage is high, and the output current is equal to the gate charge. On the other hand, when the gate-to-source voltage is high, the gate-to-drain voltage is low, and the output current is inversely proportional to the gate discharge.

In summary, the VMK90-02T2 TA is a low voltage, low power FET array that is ideal for switching and amplifying applications. Its small size and high-speed performance make it suitable for use in the telecommunications and audio/video industry. Thanks to its low input capacitance and high frequency current switching ability, this TA provides high-frequency output power and can be used in a variety of applications.
