3sk41 Datasheet 【Real – MANUAL】

: 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.

The electrical parameters of the 3SK41 highlight its optimization for low-power, high-gain signal processing. Below is a breakdown of the key data values typically listed in its technical data sheet: Maximum / Standard Value

The 3SK41 represents a pivotal chapter in the history of consumer electronics: The Golden Age of RF:

Direct high-gain, low-noise functional Japanese equivalents designed for identical RF front-end systems. 3sk41 datasheet

: The vintage metal CAN4 package isn't just for aesthetics; it provides excellent thermal protection and minimizes electrical interference. Why It’s a "Cult Classic"

The circuit uses the 3SK41 as the primary power-switching element.

The 3SK41 appears in a wide range of classic amateur radio transceivers, high‑fidelity FM tuners, and test equipment from the 1970s through the early 1990s. : The dual-gate structure allows one gate to

An older but highly capable N-channel dual-gate option often used in legacy IF/RF stages.

The is an iconic component of the golden age of analog radio design. Its dual‑gate architecture and excellent VHF performance made it a favorite for the RF front‑ends of classic amateur radio transceivers and FM tuners. While it has been obsolete for many years, its legacy lives on through the continuing efforts of restorers who maintain and repair the equipment that contains it.

Are you looking to replace an active part or doing a ? : The vintage metal CAN4 package isn't just

Due to its age, it is frequently encountered in vintage "hybrid" transceivers (like Kenwood models) and is often replaced with more modern components for better performance. Key Technical Specifications

Unfortunately, without access to a specific datasheet from a reliable source like a manufacturer or distributor, we can't provide detailed specifications here. However, typically, a datasheet for a JFET like the 3SK41 would include:

In single-gate models, the capacitance between the gate and drain is high (around 5pF), which can cause instability at high frequencies. The dual-gate structure reduces this "Miller Effect," allowing for much higher gain at 100MHz and above.

The dual-gate structure of the 3SK41 provides significant advantages in RF signal processing. Why Dual-Gate?
