The BLF8G27LS-100GVJ is suitable for use in applications such as high frequency, high voltage switch mode power supplies (SMPS), RF amplifiers, RF receivers, RF transmitters, and RF switching. It is designed to support a maximum frequency of 6 GHz, allowing it to operate in a variety of applications at high speeds.

Due to its high linearity, the BLF8G27LS-100GVJ is also suitable for use in high power linear and high power switching applications. This makes it ideal for high frequency, high voltage switch mode power supplies (SMPS), cellular and consumer base transceiver stations (BTS), microwave radios and amplifiers, as well as military communication devices.

The device is also suitable for use in other high-power hardware, such as motor controllers, direct current (DC) motor drives, television equipment, laser printers, power converters, digital video applications, and medical equipment.

Working principle

The BLF8G27LS-100GVJ is an N-channel enhancement-mode lateral MOSFET. It works by utilizing a thin oxide layer to control the flow of electrons between the gate and the source. The potential difference between the gate and the source causes current to flow across the oxide layer, which in turn allows the gate to modulate the drain-source current. This modulation of the drain-source current allows the MOSFET to act as a switch or an amplifier depending on the application.

The operating frequency of the device can be adjusted by changing the gate voltage, which in turn changes the capacitance between the gate and the source. This capacitance affects the transit frequency, which is the frequency at which current begins flowing through the MOSFET. The amount of current that is allowed to pass through the MOSFET can be adjusted by varying the gate voltage, allowing for very precise control of the power output and efficiency of the device.

The BLF8G27LS-100GVJ is capable of operating with very low input power and can reach a maximum output power of up to 0.25 watts. It has a low threshold voltage and can achieve a maximum drain-source voltage of 10 volts. The device features high linearity and high gain, enabling it to provide significantly better linearity and efficiency than other similar devices.
