3sk41 Datasheet Today

The is a classic N-channel dual-gate MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) that has long been a staple in high-frequency applications . Primarily designed for VHF (Very High Frequency) amplifiers and mixers, it remains a point of interest for hobbyists, vintage radio restorers, and engineers working with legacy RF circuits.

Utilizing Gate 1 for the RF signal and Gate 2 for the Local Oscillator (LO) to produce an Intermediate Frequency (IF). 3sk41 datasheet

Acting as the first stage of amplification. Acting as the first stage of amplification

The 3SK41 usually follows the standard TO-72 four-lead configuration. Looking from the bottom (pins facing you), the leads are typically arranged as follows: Its dual-gate construction is its defining feature, allowing

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.

Providing stable, high-frequency oscillations. 6. Alternatives and Equivalents

Facilitates easy Automatic Gain Control (AGC) and mixing functions.
