The dual-gate architecture of the 3SK41 provides a significant edge over standard single-gate MOSFETs in RF environments:

is a specialized N-channel silicon dual-gate MOSFET primarily used for high-frequency applications like VHF/UHF amplifiers and mixers. Often manufactured by companies like
If you vary VG2 from 2V to 6V, the forward gain (Yfs) changes by a factor of 10:1. This allows a receiver to automatically reduce gain when a strong signal is present.
: The dual-gate structure allows one gate to receive the RF signal and the other to receive the Local Oscillator (LO) signal, resulting in efficient mixing. Drain (D): The output lead
The 3SK41 is a JFET (Junction Field-Effect Transistor) used in various electronic circuits. If you're looking for information on this component, you've come to the right place. Below, we'll provide an overview of the 3SK41, its features, and its datasheet.
Employed in radio stages to reduce internal noise and prevent front-end overload.
In a typical RF amplifier stage, the Drain of the 3SK41 will be at a positive voltage (e.g., 12–14 V in many Kenwood transceivers), while the Source is near ground potential. A sudden loss of signal, a drop in gain, or excessive noise are often the first signs of a failing 3SK41 in vintage equipment.
The 3SK41 is housed in a standard TO-72 metal can package. Its dual-gate construction is its defining feature, allowing for superior gain control and reduced feedback capacitance compared to single-gate FETs. Ideal for front-end RF amplification.
Excellent vintage alternative tailored specifically for RF preamplifiers. SOT-143 (SMD)
