The 2N5486 is a silicon N-channel junction field effect transistor designed for RF amplifier and mixer applications. When the gate voltage is zero, it is off and requires a positive gate voltage to turn on. This transistor has high breakdown voltage, drain current and power dissipation capabilities, allowing it to operate stably in the VHF/UHF frequency range. The 2N5486 transistor is rated for 25 V and 30 mA. At the same time, it dissipates up to 350 mW of power, which means that it will not overheat even if it consumes up to 350 mW of power during operation.

2N5486 is manufactured by ON Semiconductor. It is an American semiconductor supplier, formerly the semiconductor component division of Motorola Group, with industry leading positions in automotive, industrial and cloud power semiconductor components.

2N5486 is a common transistor with three pins, namely source, gate and drain. The source is usually connected to the ground of the circuit to provide a stable reference level for the entire circuit. The gate is a conductive area covered by an insulating layer. By adjusting the gate voltage, we can control the switching state of the transistor. The drain is the output pin of the current, that is, the result of the transistor's operation is output through the drain. Its name and description are as follows:

Pin 1 (Drain): The drain terminal is the current inlet of the JFET device.

Pin 2 (Source): In the source, terminal current flows out from the JFET.

Pin 3 (Gate): Gate is used to trigger the MOSFET device.

• It operates well in VHF/UHF frequency range.

• Has relatively large drain current, ID=30mA

• Has high breakdown voltage, VDG=25V

• Has large power dissipation capability, PD=350mW

• Has high input impedance. It exerts very little loading effect on the input signal, thus maintaining signal integrity. When using this amplifier, the impact on the amplified signal can be minimized, resulting in more accurate amplification results.

• Due to its junction structure, 2N5486 has high reliability and stability. It maintains good performance even during long-term use.

• The 2N5486 is a bipolar transistor that can switch between NPN and PNP types and therefore can be used as a replacement for both transistors. This transistor is available in a variety of voltage and current specifications to meet different application needs.

• The 2N5486 transistor can usually withstand a certain voltage and power. This makes it suitable for use in some high frequency, high power or high voltage applications, especially in amplifier and RF applications.

• 2N5486 is a high-performance low-noise transistor suitable for high signal-to-noise ratio applications, especially suitable for RF amplifiers and receivers where signal accuracy is critical.

In order for the 2N5486 to work properly, we need to apply the appropriate voltage between its gate and source. The size of the gate voltage directly affects the current between the drain and source. By adjusting the gate voltage, we can control the current flowing through the device. MOSFET is usually used for voltage control, so it usually needs to provide the appropriate voltage to control the current.

1. Wireless communication field

(1) Mixer and frequency conversion: We can use the characteristics of 2N5486 to realize frequency conversion processing of signals, thereby converting signals to different frequency ranges for transmission and processing, and improving the performance and anti-interference ability of the system.

(2) RF amplifier design: 2N5486 has high breakdown voltage, drain current and power dissipation capability, and can work stably in the VHF/UHF frequency range. Therefore, in wireless communication systems, we can use 2N5486 to design radio frequency amplifiers to amplify the received weak signals and process and analyze them.

2. Radar and electronic warfare systems

In addition, it can also be used to implement signal amplification and mixing functions to improve system performance and anti-interference capabilities. For example, in radar systems, 2N5486 can be used for amplification of transmitted signals and noise reduction of received signals. In electronic warfare systems, 2N5486 can be used to interfere with enemy radar and communication systems.

First, we must thoroughly examine the components to verify the conformity of the supplier-provided transistor model with the required specifications, while also confirming the integrity of its appearance. Subsequently, we position the transistors on the PCB to ensure correct connectivity with other components. Additionally, we need to address thermal concerns to prevent transistor overheating and potential damage. Next, we employ professional welding tools and materials, adhering to the specified welding time and temperature. Once assembly is finished, we conduct a comprehensive assessment of the circuit's functionality. In the event of abnormalities, we scrutinize soldering points and other component connections for accuracy.
