Transistors are essential components used in a variety of digital circuits. Of the different types of transistors, Bipolar Junction Transistors (BJT) have been in use for many years due to their small size, large variety of applications, and low cost. Among the types of BJTs, the BC858C RFG, a single-junction transistor, stands out for its versatile application fields and easily understandable working principle.

The BC858C RFG, manufactured by NXP Semiconductors, is designed to be operated at low frequencies. It is a small-signal amplifier that combines robustness, lower dynamic resistance, and decreased current gain, allowing it to work perfectly at frequencies up to 100MHz without distortion. This remarkable versatility makes the BC858C RFG ideal for applications such as antennas, broadcast receivers, surveillance systems and satellite communication.

The BC858C RFG works based on a two-transistor push-pull amplifier. It works by using the two transistors to drive a load, which is in this case an antenna, at a fixed frequency and amplitude. In a push-pull amplifier, the input power from a source is split into two paths, one going through each of the transistors and into the antenna. Two output signals, one being the same as the original input, go through the same two transistor stages and into the load. Because of this, an impedance transformation is effected. This allows the BC858C RFG to be used with other output stages that would not interfere with the impedance of the antenna.

The BC858C RFG is also designed with a number of features to ensure it is robust in a variety of conditions and applications. These features include: reduced temperature drift, increased thermal and electrical reliability, improved input matching, and minimized noise and distortion. These features combine to make the BC858C RFG a reliable, robust and efficient device for a variety of applications.

The BC858C RFG is one of the most versatile, reliable, and cost effective transistors on the market, making it a popular choice for many applications. Its small size, broad application field and easily understandable working principle make it an ideal choice for a variety of projects. Any project requiring a stable, reliable and cost effective transistor should seriously consider the BC858C RFG.
