Application Field

The PTFB193404F-V1-R0 is designed for a wide range of RF applications, such as mobile communication, WLAN, satellite communications, RF transceivers and military equipment. As it has low gate threshold voltage and low on-resistance, it is also suitable for switch mode power amplifiers or as a signal chopper in harsh environment.

Working Principle

The PTFB193404F-V1-R0 operates on the principle of Metal-Oxide Semiconductor Field Effect Transistor (MOSFET). A MOSFET consists of two terminals, the source and the drain, and is designed with a thin layer of metal oxide which acts as a gate between them. A voltage applied to the gate electrode creates an electric field that modulates the conductivity of the drain to source channel.

When no voltage is applied to the gate, the transistor is in the "off" state, blocking current from flowing between the source and the drain. On the other hand, when a voltage is applied to the gate, an electric field is created that modulates the conductivity of the drain to source channel, enabling an electric current to flow through it.

The PTFB193404F-V1-R0 is also designed with low on-resistance and low gate charge, which enables it to be used for high-speed applications. Additionally, it has a very low input and output capacitance, making it highly suitable for RF applications, where high levels of switching and noise performance are needed.

Conclusion

In summary, the PTFB193404F-V1-R0 is an advanced Silicon N/P-Channel RF MOSFET, ideal for a wide range of RF applications. It provides excellent RF performance at 4GHz, with its low on-resistance and low gate charge, making it suitable for both high-speed applications and switch mode power amplifiers or signal choppers.
