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

Used as a low-noise RF amplifier to improve signal reception. 3sk41 datasheet

Acting as the first stage of amplification. Utilizing Gate 1 for the RF signal and

Facilitates easy Automatic Gain Control (AGC) and mixing functions. 3sk41 datasheet

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:

Modern silicon N-channel dual-gate MOSFETs (though they often come in SOT packages).

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.
