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
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
: By varying the voltage on the second gate ( VG2Scap V sub cap G 2 cap S end-sub ), the gain of the transistor can be easily controlled. The second gate (Gate 2) is specifically designed
