Description

BFW10 is N-Channel JFET for VFH/UHF Amplifier.

An N-Channel Junction Field-Effect Transistor (JFET) can be used as a VFH/UHF (Very High Frequency/Ultra High Frequency) amplifier. JFETs are semiconductor devices that can be employed as voltage-controlled resistors, and they are commonly used in various electronic applications, including amplifiers.

For VFH/UHF amplification, JFETs offer certain advantages. They have low noise characteristics and can operate at high frequencies, making them suitable for amplifying radio frequency (RF) signals in the VFH/UHF range. N-Channel JFETs are preferred in this context because they are more commonly used for amplification applications.

The N-Channel JFET is controlled by a voltage applied between the gate and the source terminals. When a voltage is applied to the gate, it modulates the flow of current between the drain and source terminals, allowing the JFET to function as a variable resistor and amplify the input signal.

Maximum Ratings:

1. Drain-Source Voltage : Vds = 30 Vdc

2. Drain-Gate Voltage : Vdg = 30 Vdc

3. Reverse Gate-Source Voltage : Vgsr = -30 Vdc

4. Forward Gate Current : Igf = 10 mADC
