By varying the DC bias voltage applied to Gate 2, you can seamlessly control the overall gain of the amplifier stage without heavily detuning the input tank circuit attached to Gate 1. Common Applications

However, I can guide you on how to find datasheets for electronic components:

The 3SK41 datasheet highlights several critical parameters that make it suitable for VHF and UHF amplification. 20V (Maximum) Gate-Source Voltage (Vgs): 7V (Maximum) Drain Current (Id): 25mA Power Dissipation (Pd): 250mW Forward Transfer Admittance (gfs): 8.0mS (Minimum) Input Capacitance (Ciss): 5.0pF (Maximum) Case Type: CAN-4 or TO-72 (4-lead metal package) Key Features & Applications 3sk41 datasheet
