The MRF5S19150HR5 is a high-power silicon N-channel lateral MOSFET (metal oxidized semiconductor field-effect transistor) developed for cellular base station RF power amplifiers, in particular for handset and low-power base station applications. It is intended for use in a wide range of applications, such as driver amplifiers and output stages in both high and low power, amplifier linearization, and power supply regulation. In this article, we will discuss the application fields and working principle of MRF5S19150HR5 MOSFETs.

The MRF5S19150HR5 MOSFET is designed to provide superior performance in the harsh RF environment of today’s base station systems. It offers 20 volts of drain-source breakdown voltage and integrated ESD protection, providing protection from electrostatic discharge (ESD) hazards. The RF MOSFET achieves class-leading SFDR performance, with exceptional maximum reverse recovery time of only 80ns. In addition, this device features an extremely low gate charge and low gate-to-drain capacitance. This is critical for base station applications as it maximizes gate drive current efficiency and reduces the resistance to signal transmission.

The MRF5S19150HR5 can be used in a variety of applications. It is suitable for RF, mixers, transmitters, amplifiers, power supplies, and other high-frequency switching, linear, and power applications. It has applications in cellular base station as amplifier, RF power amplifier, driver amplifier, and output stages at both high and low power. It is also suitable for applications such as amplifier linearization and power supply regulation. As a result, this device is ideal for both mobile and low-power base station applications.

The MRF5S19150HR5 utilizes an advanced device architecture that includes an independent source along with the internal connection of the source and drain regions, which are electrically 30% longer than traditional MOSFET structures. This helps to minimize capacitance, resulting in superior performance at higher frequencies. In addition, the device also features integrated ESD protection and a maximum drain-source breakdown voltage of 20V.

The working principle of the MRF5S19150HR5 is similar to that of other MOSFETs. It uses an insulated gate to control the flow of current between the source and the drain. When a voltage is applied to the gate, the amount of current that can flow between the source and the drain is determined by the voltage applied. As the voltage increases, the current will increase as well. Conversely, as the voltage decreases, the current that can flow decreases until it reaches the device’s threshold voltage, at which point the current is completely blocked.
