The MRF392 is a type of transistor in the bipolar junction transistor (BJT) family, specifically designed for use in radio frequency (RF) amplification and switching applications. It is composed of two NPN transistors and one PNP transistor all integrated in a single 7-pin, low-cost package. It is also known as a monolithic microwave integrated circuit (MMIC).

The MRF392 has a maximum operating voltage of 50 volts and a maximum collector current of 375 milliamps, allowing it to be used in many high-power applications. The device provides moderate gains of about 16dB at 900MHz at a current consumption of only 500 mA. The transistor is also capable of operation up to 4GHz, making it suitable for use in many RF applications. Its low frequency response is also impressive, allowing for reliable operation at frequencies as low as 50MHz.

The MRF392 works in a common base configuration, using three separate diodes to create the three regions necessary for biasing the 2N3904 NPN transistor and 2N3906 PNP transistor, while also providing protection against over-current and reverse-bias junction breakdown. The device also has three separate bias resistors (R1, R2, R3) with variable gate-source voltages, allowing the user to adjust the voltage/current applied to the base region of the transistor to provide amplifier gain control. Once the correct bias voltage is applied, the PNP transistors act as switches, allowing the NPN transistors to be used to amplify the RF signal.

The MRF392 is primarily used for high-power radio frequency amplification and switching applications. Examples of these applications include power amplifiers, repeaters, wireless link systems, and automotive radios. The device is also used in test equipment, including spectrum analyzers, mixers, and RF power meters. Due to its high current and frequency range, the MRF392 is also frequently used in satellite communications systems.

In summary, the MRF392 transistor is a 7-pin, low-cost packaged device specially designed for radio-frequency amplifier and switching applications. The device has a maximum operating voltage of 50 volts and a maximum collector current of 375 milliamps, allowing it to be used in many applications. Its common base configuration and three bias resistors give the user control over the gain of the amplification. The device is ideal for high-power amplifications and switching tasks, such as amplifiers, repeaters, and wireless link systems.
