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

The 3SK41’s two gate terminals are its defining feature. In a typical dual‑gate MOSFET, is the input that receives the RF signal to be amplified, while Gate 2 is used for a control voltage. By varying the voltage on Gate 2, the circuit can adjust the transistor’s gain, a technique known as Automatic Gain Control (AGC) in receivers. This allowed radio designers to build simpler and more sensitive front‑ends for FM tuners without relying on variable attenuators or multi‑stage control loops.

Mixing an incoming RF signal on Gate 1 with a Local Oscillator (LO) signal fed into Gate 2 to generate an Intermediate Frequency (IF).
