3sk41 Datasheet
Providing initial signal boost for weak radio waves.
: Excellent for sensitive, low-level signal detection.
The foundation of any datasheet is the component's electrical limits. While a complete official datasheet is no longer publicly available, key parameters have been meticulously compiled from reliable, cross-referenced sources.
) is kept under 5.0 pF, it causes very little loading on input tuning networks. 3sk41 datasheet

Later generations of Japanese dual-gate GaAs FETs with similar or improved UHF performance. Providing initial signal boost for weak radio waves
To achieve the low noise figure and high gain specified in the datasheet, design accurate LC matching networks for both the input (Gate 1) and output (Drain).
Used for general-purpose signal conversion and switching in alarms and security systems. Datasheet Resources
