This document describes the features of BF 998R silicon N-channel MOSFET tetrode, suitable for low noise, gain-controlled input stages up to 1 GHz.
This document describes the Siemens BF 998R, a Silicon N-Channel MOSFET Tetrode. It is characterized as a short-channel transistor with high S/C quality factor and is designed for low noise, gain-controlled input stages operating up to 1 GHz.
The datasheet notes that this is a reverse pinout version of the BF998 type. All electrical data for the BF 998R are stated to be identical to the corresponding type without the 'R' suffix.
It is a silicon N-channel MOSFET tetrode.
Pin 1 is Drain, Pin 2 is Source, Pin 3 is Gate, and Pin 4 is Ground.
The device uses an SOT-143R package.
