The 3SK41 solves this by using two independent gates in a series configuration resembling a cascode circuit: acts as the primary signal input. Gate 2 ( G2cap G sub 2 ) acts as an RF shield between Gate 1 and the Drain.
: Provides significant amplification, especially in VHF bands. 3sk41 datasheet
The 3SK41 was also used in television front‑ends and VHF converters. It is known to be cross‑referenced with devices such as the BF960 , which was found in many European TV channel selectors from the same era. The 3SK41 solves this by using two independent
