The MMBF5484 is a N-channel depletion mode transistor designed for use as a high frequency switch, RF amplifier and oscillator. It is also commonly used for microwave and high voltage switching applications. It’s a versatile, low cost, low power solution for RF frequency switching and amplifying.

The MMBF5484 is a versatile, wide operating temperature range transistor capable of 0 to 6V operation. It is a 30V N-channel enhancement mode MOSFET with an enhancement factor (Vgs/Vds) of 2V-6V, making it ideal for many high frequency switching applications. The device has a low on-resistance of just 0.65Ω and a maximum power dissipation of 0.3W, making it a very efficient device for high frequency switching and amplification.

The MMBF5484 is a depletion-mode FET, meaning it requires the gate voltage to be less than the drain voltage for the transistor to be in the active region and the device conducts. When the gate voltage is increased, the device is switched off and no current flows through it. This makes it an ideal switch for high frequency applications. The device also has an excellent transition time of just 7µs and low gate capacitance of just 15pF, making it extremely fast and responsive.

The MMBF5484 is a very robust device and can tolerate very high voltage and power dissipation. It is suitable for use in applications such as high voltage switches, RF amplifiers, oscillators and mixing circuits. The device can also be used as a high frequency switch, where it can safely switch high voltages and currents. It is also suitable for use in radiation-sensitive applications, such as in mobile phone and satellite communication systems, as it can tolerate high levels of radiation.

The MMBF5484 is a versatile, low power and cost-effective device, making it ideal for many applications, including those where a high frequency switch is needed. It can be easily integrated into existing circuit designs, making it a great solution for designers looking for increased switching accuracy, response time and signal integrity.
