MRF7S35015HSR5

The MRF7S35015HSR5 is a type of Field Effect Transistor, commonly referred to as a FET. Specifically, it is a type of Metal Oxide Semiconductor Field Effect Transistor, or MOSFET. It is designed for use in radio frequency (RF) applications and is considered a high power device.

Application Field

The MRF7S35015HSR5 is commonly used in a variety of RF applications. It is mainly utilized when high power output is desired, such as in high power amplifiers, radio transmitter drivers, and low noise amplifiers. In addition, this MOSFET can be used for high efficiency power conversion, in power combiners, and in switch mode power supplies.

Working Principle

The MRF7S35015HSR5 operates by having a dual-gate MOS structure. This means that, instead of the standard one gate found in most FETs, this MOSFET has two gates – one on the source and one on the drain. By having two gates, this MOSFET can handle higher power than a single gate FET and reach a higher frequency.

In operation, the gate-source voltage (VGS) controls the drain current (ID) flowing between the source and drain. This current is determined by the gate voltage and the gate capacitance (CG). The drain voltage (VDS) also affects the current flow, however, this is only true if the maximum drain-source voltage (VDSS) is not exceeded. Below this threshold, the current flow is largely dependent on the VGS voltage.

The high frequency performance of the MRF7S35015HSR5 is its main advantage. This MOSFET has a high slew rate and a low noise figure, allowing it to operate up to 5GHz with high efficiency. The high frequencies it can handle make it the perfect choice for high power RF amplification.

Conclusion

The MRF7S35015HSR5 is a dual-gate MOSFET designed specially for high frequency RF applications. It can be used in a variety of applications, including high power amplifiers, low noise amplifiers, and even switch mode power supplies. Its main advantage is its high frequency performance, allowing it to handle up to 5GHz of power, making it perfect for high power RF amplification.
