3sk41 Datasheet Fix Jun 2026

The second gate acts as a shield between the input gate and the drain, significantly reducing Miller effect capacitance. This provides better stability and higher gain at VHF frequencies. Automatic Gain Control (AGC):

In RF receivers, one gate can be used for the signal input while the second gate handles an AGC voltage. This allows the circuit to dynamically adjust gain based on signal strength without detuning the input. Mixing Capabilities: 3sk41 datasheet

The is a high-performance Silicon N-Channel Dual Gate MOSFET typically used in high-frequency (RF) and microwave applications. It is manufactured by companies including NEC, Hitachi, and Motorola and is often housed in a CAN-4 (similar to TO-72) metal package. Key Features & Applications: The second gate acts as a shield between

The 3SK41 is known for its linear transfer characteristics. This reduces the likelihood of "intermodulation distortion," ensuring that strong nearby signals do not drown out the weak signal you are trying to receive. 📐 Pinout and Package Information This allows the circuit to dynamically adjust gain

The second gate (Gate 2) is specifically designed for Automatic Gain Control (AGC). By varying the voltage on Gate 2, the gain of the amplifier can be adjusted without significantly shifting the input impedance or frequency response. 2. Low Feedback Capacitance

Its dual-gate design allows for efficient automatic gain control (AGC) or local oscillator injection without compromising stability. Sourcing & Replacements
