Often tied together to provide grounding and shielding. Drain (D): The output lead.

Acting as the first stage of amplification.

Minimizes loading on preceding stages. 2. Technical Specifications (Absolute Maximum Ratings)

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

The is a classic N-channel dual-gate MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) that has long been a staple in high-frequency applications . Primarily designed for VHF (Very High Frequency) amplifiers and mixers, it remains a point of interest for hobbyists, vintage radio restorers, and engineers working with legacy RF circuits.

(Note: Always verify the pinout with the specific manufacturer’s marking, as some variations exist.) 5. Common Applications

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

): Extremely low (approx. 0.02 pF), which is vital for stability in high-frequency amplifiers. Typically 2.0 to 3.0 dB at 200 MHz. 4. Pinout Configuration
