Verified — 3sk41 Datasheet

Another excellent legacy RF/IF amplifier alternative that maintains high gain profiles across similar frequency bands.

Gate 2 can be used for Automatic Gain Control (AGC), allowing the amplifier's gain to be adjusted without significantly affecting the input impedance.

): Max 5.0 pF. Minimal capacitive loading preserves high-frequency bandwidth. Max 4.0 V. Conduction Efficiency: Designed with a minimized 3sk41 datasheet

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 3SK41 has been found in numerous high-end electronic devices from the 1970s and 1980s. It is often located on the RF amplifier board or the front-end tuner module. Common applications include: The 3SK41 has been found in numerous high-end

Thanks to its dual-gate design, the 3SK41 excels in roles where single-gate FETs require complex external neutralizaton circuits. VHF/UHF Amplifiers
